I need to do the NO CONTACT LAST RESORT thing and not text or call him at all and not try to engage him at all in conversations when we are together. Let him engage me and then respond shortly and sweetly then move on.
Make it shorter goals. Try one day to not be the one to contact him. Handle anything yourself, and then move to the next day. Don't let yourself get angry between when he isn't contacting you. It will affect your next contact. It is so very hard!
