So to start I'm 17.
I've been with a girl for 2 years and I now am unnatracted to her.
She's a little overweight but usually I'm attracted to girls with a little bit more to them.
I just don't know what to do I'm a really even guy and I like to think things through before I do anything but for the past month or so I've been thinking about leaving her but me and her have always gotten along so well but I'm just not attracted to her anymore.
She may have gained a little weight but if she did its not something I noticed when I looked at some older pictures.
We don't see each other to often (3-6 times a month) but when we do its for a few days in a row and we have sex often and it feels really good.
I just don't find her attractive anymore.
Maybe its stress or maybe it's that I lost 60 pounds a few weeks ago and she always says shell lose weight (which I have never even thought of telling her she needs to do) and never doing it but I'm just very worried about ending this relationship and realizing it was a bad move and need more experienced people to help me out
Please by all means ask for more information and ill tell you almost anything I just need help...

When you are 17, the chances of being attracted to the same person for very long are almost zero. Don't worry about it. Just be as nice as possible when you explain that you like her and hope you can remain friends. If she is too upset, break it off without further contact to do her the favor of not dragging it out.

Maybe don't tell her that you're not attracted to her anymore, it'll hurt her feelings and make her doubt herself and her confidence (this has been said to me before, ouch!). Just end it in the nicest way possible, explain that you feel its not working out anymore and then give her a lot of space, don't call/text etc. You are so young and so is she! She will find somebody who finds her attractive and she deserves to have somebody who does! Also if you care about her you'll allow that to happen for her :) And then meanwhile you go find somebody hot and enjoy yourself!
