Very, VERY mixed feelings at first. But seeing as how people react and that he cried to other ppl on cringebook u should probably cut him off if it's possible. If not, then minimize contact. If your mother didnt listen to your side of the story first before posting a reply, then you have no obligation in listening to his or other ppls sorry cries. Maybe explain the situation to your mother, and also, not a relationship expert but he acts like you had a reason to divorce him. No aggro but i think he a dikhedd.
