I've been with my current girlfriend for almost 2 years now. For the first year I thought she was the love of my life and the most beautiful girl in the world. Now, though, I don't find her attractive anymore. I don't think her appearance has changed that much, maybe she's gained a bit of weight but I don't think that's it. Of course it's more than looks, I just don't know if I'm still in love with her. I'm always catching myself fantasizing about dating other girls I know, like 'if only I wasn't tied down' sort of thing. But I still have feelings for my girlfriend, I care about her a lot, we shared some great things - she's probably the only one on this planet I can confide in and really talk to, which is what makes this so painful. A part of me is saying I should break up with her, but another part of me is worried that I'll regret it for the rest of my life. If I lose her, then I've got nobody.
