AITA For Not Telling My GF Why I’m Tall?

He was just a young man chasing his dreams abroad, starting university with the excitement of newfound independence and a surprising growth spurt that seemed like a blessing at first. What began as a thrilling change in height soon spiraled into a silent battle with mysterious migraines and dizzy spells, a hidden storm brewing within that no one saw coming.

As his body continued to grow beyond the ordinary, the shadows of uncertainty crept in, culminating in a devastating diagnosis—a tumor on his pituitary gland. The journey that started with hope and excitement now faced a daunting fight for health and normalcy, testing the strength of both him and those who loved him.

AITA For Not Telling My GF Why I'm Tall?

I’m M23 and my GF is f24 we’ve been together for a year. Back when I was 18 I went abroad for uni and I started getting taller slowly at first, I was about 5’5 when I left and slowly after about 7 months I was 5’10.

I went to the Dr in the country I was studying in and they assured me I was in puberty still and I’m just getting taller. I went home for the summer and everyone was surprised that I’m like a normal height now and it was nice being taller.

I had no medical symptoms so didn’t go to the Dr in my country since I was healthy. I was still growing slightly and I was around 6ft tall when I left back to go abroad for school in the fall.

Once I got back to school I started having a lot of migraines and dizzyness etc. It was pretty mild so I stupidly ignored it for a few months but I was still growing and about 6’2 by the winter.

I went to a large hospital near my uni instead and they gave me a brain scan and MRI and they discovered I had a smallish tumor on my pituitary glad and this was causing my symptoms and crazy height gain.

The tumor was stimulating the gland to release high amounts of HGH. I flew back home ASAP and my parents took me to the hospital and thankfully it was benign and it was removed easily.

So after all that I’m 6’3.5 after about 2 yrs of having this tumor while both my parents are 5’3. So I was destined to be short and all my kids probably were too.

I met my GF last year and I basically have no health problems from it, I just go in for check ups on my hormones and a brain scan every 6 months. I told my GF that I had a brain tumor but it wasn’t a big deal and she didn’t care too much about it since we dealt with it.

I didn’t tell her it caused me to get tall because idk she never asked and none of my friends or family cared and no one talks about it.

She found a picture of me at my prom and I looked really short and she was like wow you grew so much and I told her ya its because of that tumor I told you about. She was surprised and asked more about it so I non chalantly told her what happened and how I would have been 5’5 if it didn’t.

To my surprise she got mad and said that I was lying to her about my height and that if we had kids they would be short since everyone in my family is. Which is true my genes didn’t change, my kids would probably also be short.

Called me a huge asshole and has been distant with me for a couple of days.

For context she’s 5’6

Here’s how people reacted:

NTA You didn’t have to assume your girlfriend was just looking for a sperm donator coming from a line of tall people to sire her future offspring for prime breeding results.
Also, while genes do matter you never know 100% what’s in the mix. My husband and I are both rather tall (with him at 185cm and me at 173cm) and our kids aren’t really. Our son is about 178cm and our daughter isn’t even 160cm tall… Looks like some genes frim my parents (both not tall) came through…
However, I wish you all the best and hope your girlfriend will realise how out of line she was and will apologise.

100% NTA.

You can’t control the TUMOR that grew in your BRAIN. How can you lie about your height? Are you kidding me?

My brother is 6’8”, and he has a son that’s only 5’7”. Genes wouldn’t guarantee a short/tall child anyways— it increases the likelihood, that’s about it.

If she was so perfectly happy to be with you before, and is now NOT happy since a completely out of control circumstance made you taller, she’s not a girlfriend, she’s a shallow pile of red flags.

NTA, but gf sounds very immature. It is real easy to prove your story as true. Show her the medical records. And, if you two did stay together, and did have kids, they could get their height from their mom.

Now, both my mom and my dad were 5’2″. All but me and my brother are shorties like they were. The rest of my brothers were 5’6″ and above. Somewhere down the line, there are some distant relatives that have some height on them.

It seems like you’ve disclosed plenty about yourself to her — about you having a tumor, etc. And likely she’s seen pictures or met your parents also. Her considering the potential height of your potential kids is just very weird and entirely off as far as relationship material goes. You are not a breeding stallion for her to need the exact heights of all of your relatives.

Unless the circumstances of you starting the relationship was fully based on finding a bio dad to future children (think Fundie Courship) you had no obligation to treat yourself like breeding stock.

Run… far far away.

serjaf

NTA, she can be taken aback as this is new and something to process. But getting frustrated or angry at you? Nope, this just means she is shallow. She should be happy you’re healthy now.

And also: 🚩🚩🚩🚩🚩🚩🚩🚩

alwaystired7

NTA why does she care so much about how tall your hypothetical kids would be? It’s not like shorter people have horrible lives. And for her to accuse you of being a liar is a real overreaction on her part.
PasDeTout

NAH. If the height of any future children are important to her then she will deliberately choose a tall man. To be angry about it is an overreaction: it’s not like you lied to her.

It’s weird, because you’d think being taller (and therefore, having more volume) would make it *harder* to dodge a bullet, not easier, as it was in your case.

Cory-gang

NTA. I find this super weird and not important. Your girlfriend is super immature. P.S. she dropped several of these 🚩 🚩 🚩

Conclusion

The central conflict revolves around the Original Poster’s (OP) decision to withhold information regarding the medical cause of his significant height gain from his girlfriend. While the OP believed the topic was irrelevant after the tumor was removed, the girlfriend views this omission as a form of dishonesty about his fundamental physical characteristics, especially concerning potential future children.

Is the OP justified in withholding details about a resolved medical issue that altered his natural height trajectory, or was the girlfriend’s reaction an overblown response to information that does not affect the current health or stability of their relationship? Should prospective partners be entitled to complete disclosure regarding all past medical events, regardless of current relevance?
