My girlfriend and I have been dating for almost two years now and I thought everything about our relationship was amazing until about this past october. I felt we both were rational people (a huge point for me because I always try to think rationally and with caution), we have intelligent conversations, we both love movies, and music, but I have always felt something was wrong. I think it had to do with our political and religious beliefs not lining up. I ended up breaking up with her in october, 2012 for about three days. I felt like I needed her back and that I loved her more than anything. But now, I am starting to experience the same type of doubts in our relationship again. I love her a lot, but not as much as she loves me. But to throw in some more confusion, I constantly notice other girls at college and want to flirt with them, but I do not because I am faithful. Also, we plan to go long distance by the time I transfer and she goes to college for the first time. I am not sure if I am comfortable with that. I keep thinking that I need to date more to find what I really want in a relationship since I have only had two serious relationships, which were both at a young age. Any advice?
<bot>: I have many doubts that mainly include social issues and an upcoming long distance relationship about relationship with my girlfriend of about 2 years, but I feel i may be making a mistake if i break up with her for good. Advice?
