I'm dating this guy. He was together with this girl for about a year and they broke up. He asked me out about 3 months after they broke up and he's friends with her and goes to her house a lot. I feel like I'm a rebound for him because he told me he didn't really have a reason to date me, he just asked me out for no real reason. He's with her a lot and it gets to me at times. Today is New Years and he chose to spend it with none other than her. I'm pretty down about it but there's nothing I can do. I can't just tell him he can't be around her. I love him but I can tell he doesn't really feel the same or care for me. I am thinking I might want to break up with him but at the same time I'm afraid to and don't want to leave him because I care about him. I don't know what to do. Should I break up?
