I wish someone had a magic wand that they could wave that would just make everything perfect but I know that's not going to happen. I really appreciate you taking the time to respond to my post.
Maybe ask him why he likes being with you? It sounds like insecurity is driving many of the feelings you have about this. If you were to know why he really loves you and being with you, then it may not hurt so much. In a sense, this other person can not take anything away from your relationship with him.
I hope this works out for you.
