every time we went out he would get annoyed that guys would stare at me and sometimes they would hit on me right in front of him. I was all about my boyfriend . When we broke up he didn't give me a reason. We ended up hooking up the rest of summer bad idea. Now that I'm back at school he has a new girlfriend who no offense plain says my guy friends.would a guy seriously break up with a girl because he get a lot a male attention?
