It sucks right now but give it some time and you'll realize what a blessing this is.
When I have gone no contact it has never been about the other person, they just remind me too much of who I was with them. Don't take it personal.
I used to run into XABF often even infront of each other and he always looked away. Its because I am his mirror. He can fool others that don't know him but he sees who he is by looking at me, remembering what he did and what he said. So, he looks away.
Anyway its been 2 years of No Contact and I have been given so many blessings and met wonderful people that SEE ME and value me and help me to learn to RECEIVE and RELAX in friendships and in life in general. EX? he keeps being a jerk and drinking and denying any issue. He is God and he can do what he wants when he wants it. Fine.
I no longer have patience for people like that. I was, and am worth so much more than that.
