I think I love him, but I'm crushing on another guy.....?

I've been with my boyfriend for 2 years now, we've seriously talked about moving in together, marriage, etc.. for the past few months I've been playing doctor phil for a good guy friend, I've been having mixed feelings for him... I want to say I love my boyfriend, but with this other guy it feels special too. I've slept with neither of them, I'm waiting till marriage, so, sex is not an issue. I think my love might be waning.. We broke it off this morning and we're both hurting very badly over it. I just wanted a bit of advise and general opinion..
