That you develop feelings for someone else doesn't say anything about the relationship with your BF, at least not to me.

If not for him almost cheating on you, I'd say counseling might not be needed.

I think it is a really strong move to tell him about your feelings and your problems with it. I hope he sees it the same way and it turned out to be the right decision. I feel so many people never talk about the quality of their relationship, it deteriorates and then one person just calls it quits at some point, and this is as a clap of thunder in a clear sky to the other. You at least have to help each other be the best possible partner imaginable.

Whatever you feel, it will pass in time. Especially if you don't see him again.
