So you are stringing one guy along and jealous that another is moving along without even knowing your real feelings?
Wow, you sound amazing.
1) You are in a relationship you don’t want to be in (you are just comfortable and that’s not fair to that guy)
2) You are jealous of another guys success in moving along with his life.
3) The guy you are "obsessing" about has already told you no. "He said that it would destroy your intimate friendship”. (He was being nice about the no)
Sure go ahead tell him how you really feel. Destroy his new love life by confessing your undying love for him. Crush your current boyfriend’s heart.
Because I promise it won’t make you look obsessive or needy or controlling.
It will only increase your friends love for you and he will never resent you. He will fall in absolute love with you and you will live happily ever after.
IMO I think you need to leave the current boyfriend because he is only the good for now guy, and that isn’t right for him.
Figure out what you want in life and then do that.
The wishy-washy stuff has got to go.
Maybe there's no peace in this world, for us or for anyone else, I do not know. But I do know that, as long as we live, we must remain true to ourselves.
