I'm a male that is 17 years old, and my girlfriend is 16. We've been dating for a month and a half, and had a thing for months beforehand, and all of a sudden about a week ago my feelings for her just started to go, I think I know why- she's immature and (not to be mean) but very very very unintelligent. I am a uni student as of this year, and I'm quite mature and (not to be up myself) but I'm intelligent and like having intelligent conversations, and when I'm with her I feel like I have to tone down my vocabulary and conversation topics or almost always she "doesn't get it". For the last week I've been texting her less, and we have only seen eachother once, and she's caught on that somethings up and text me today asking if I still have feelings for her, and saying that she loves me and loves every minute shes with me, but I don't feel the same. I've met her parents on numerous occasions, her siblings love me (they're young..4/7). I don't know how to respond to her, in a way I want to break up. Every friend of mine thats met her has commented to me that she's so dumb.
The other problem is that we recently had sex, both of us losing our virginity (about a week ago) and I don't want to seem like I was just using her and am now breaking up with her because I have had her, because I'm not like that at all.
How should I go about breaking up with someone that is in love with me? I'm not a very confident person but don't want to be a wimp and do it over texting or something. Also face-to-face isn't really an option because we both live a while away and neither of us have our license, and meeting up somewhere just to break up seems silly.
Any advice on how to go about this? Should I break up with her or try harder? I really can't stress enough how hard it is to talk to her due to her low intelligence.
E.G.- (Christmas Day) Hey whats the date today?
It's christmas..surely you know the date...
No I don't what is it?
25th....

How could you not realize she was this dumb BEFORE having sex with her? You aren't kidding anyone, kid... you did wait until you had sex, and now that you got what you wanted, you want to dump her.

Anyway, you've only been dating for a month and a half, so it really won't be difficult to break up with her. Not telling her face to face is a pretty shitty thing to do though. It may seem "silly" to meet up somewhere "just to break up", but I think you owe it to her. Tell her you two need to talk and if you can meet for coffee tomorrow, or something. Then just tell her you're really sorry but you realized you don't have feelings for her anymore, so you want to break up. There's no easy way to do it, and you need to be explicit, otherwise you risk giving her false hope that some day you'll go back to her.
