This is going to be pretty long but it’s also a way for me to write down my feelings and share my thoughts to someone. So if you’re interested: 

To start off, me [17M] and my gf [17F] have been together for almost 2 years. 

From the beginning we had a very strong connection and the same opinion about pretty much everything. Stuff is great and we genuinely both love each other to the moon and back. We are both each other first bf/gf ever.
But since a couple of months ago I don’t love her like I used to anymore. And I’m not really sure why but I will try to explain the small things here. There is no ‘real’ reason, just a some small things and a strong feeling to brake up. (Which I can’t really explain)

I want to break up with her but I don’t know what to tell her because there is literally no reason to break up and I still care a lot about her. 

My gf is the sweetest girl I have ever met and does so much for me that I cannot ever return. I had a hard time with my parents divorce and she was always there for me. 

Now why I want to break up with her: 
1.    She is one year younger then I am and next year I will be in uni, which is only about 20minute drive from where we both live (Belgium is a small country) so we can actually still see each other a lot. However I will be living a totally different life in uni while she is still in high school. 

2. I (tall dude of  1m95 or 6’4”) don’t find her that attractive anymore (physically). I used to be in love with her body, she is very “round” you could say in the ‘good’ places and very small (in length). (About 1m60 or 5’4”). This body type used to turn me on like crazy. She is however not skinny, which I previously didn’t mind but she has been gaining some weight in her legs and belly recently. We used to have a lot of sex but I’m kind of turned off by her body as of lately. She is aware of this actually and is exercising and watching what she eats but still, I don’t find her body attractive any more. 

3. A lot of girls started showing interest in me. I know this is a terrible excuse to say but it is true, before her, I never had a girlfriend, never talked to other girls in a serious way. I am suddenly getting a lot of attention from other girls for some time and I would like to ‘experiment’ more in my life before I want a true partner for ever. 

Lastly I want to say that I know for a fact that my gf still loves me like crazy and will not ever see it coming if I suddenly break up with her. Her friends always tell me how happy she is with me and it breaks my heart to hear that while I’m contemplating to break up with her for some little stuff she will never see coming.

So Reddit, would I be an asshole for breaking my 2 year relationship over this ?
