Been dating for over 2 years now. I truly love my SO and she is my first girlfriend. Never cheated on her and never will. But the thing is, I think I'm still atracted to other girls. And honestly, sometimes I think I miss being single, going out and having casual sex with different people. It's not that I'm unhappy being in a relationship, I love taking care of her, spending time and talking to her every day. And I really care about her feelings, wouldn't want  to hurt her in  any way. I've never approached this with her, but lately this thought has become more frequent. WIBTA if I were honest to her about how I'm feeling and that lead to us breaking up?
