<human>: Condense the text into a few key points

First of all sorry if I'm doing anything wrong I don't really post on reddit.

Well i've been dating my girlfriend for around 5 months (i know it's not alot) everything is great we don't really argue, we make a cute couple and we've been happy together. She is a really nice girl, very respectful, beautiful, and has a great personality. She's basically everything I want in a girl. There are some things that bother me though, her father doesn't let her have a boyfriend and he is over protective. We have only been on 3 dates besides the times I've gone to eat with her on her break at work. We spent most of our time at school together but I already graduated last year. She has a best friend thats a guy, I have no problem with this because I can't control who she's friends with but it does bother me, and she has an ex who she dated for 8 months who she thinks still loves her (they're still friends but she will stop talking to him if he ever tries to get with her). She really loves me, I'm different from other guys she's dated, some of them were a-holes and I'm one of the good guys. I treat her like a queen, I do alot of little things for her that make her happy. She says she loves me to death and that i'm her other half  but I don't think that I feel the same :/

For some reason I find myself just not happy anymore. She's a real good girl, she's a keeper but I feel like I'm not the one for her. I don't know why I feel like this and now I find myself thinking about breaking up with her. 

Basically I don't know what I should do, break up with her or stay and hope my feelings come back.
