I agree with the advice given by the other members of this forum. I read and read your post and thought you did nothing wrong, in fact, I admire the way you handled the situation. I have the opposite issue, I ignore red flags repeatedly to my own detriment. Looking back, had I handled myself the way you did in this situation, I probably would have saved myself a great deal of heartbreak!

I also feel that since you both have been friends for quite a while that maybe telling him what you told us here might be a good idea to clear things up, whether you want to remain friends or want to pursue a romantic relationship with him. A friend will understand your feelings and accept them as valid. It is good to get resentments out in the open in both friendships and romantic relationships. No one can read anyone else's mind.

Be proud of yourself for exercising restraint. I am finally learning, and I have the scars of my heart to prove it.
