It seems to me like you are doing the right thing by not contacting him, my guess is he would have contacted you if he began to think differently.

You sound like you have a healthy mindset in that you are finding sources of comfort in the other important people in your life. Its good you are taking care of yourself like this and the breakup of a relationship is I guess, like grief with its different stages. Anger, disbelief, bargaining, and eventually acceptance.

I’ve seen it written elsewhere that if a person breaks up with you, they weren’t the right one for you even if you feel you were perfect for each other. He has opened up a pathway for you, after you have moved through this period of grief, to find someone who will want to stay with you and build a future with you.

I believe relationships  of any kind, family, friends, lovers ,  reflect back to us how we are in the world we learn something about ourselves and how we relate to eachother, what we need what are our strenghts our weaknesses, what we are good at bringing to a relationship. All relationships good and bad have something we can learn about ourselves and how to move forward positively into new ones.
