I told my ex when we were together, and after we broke up I would be here for him always. It has gotten to the point where communicating with each other is becoming irreparable. I feel morally obligated to continue reaching out towards him, because of how I am and what I have always promised him. I don't know if I should try anymore, or give it all up once and for all even though I'm not fulfilling my promise. I just feel like he needs me, because he's vulnerable regardless of how harsh he is acting now. I'm not even trying to get back together with him hardly, I'm just wanting better communication but he keeps pushing back. What should I do? Thank you.
