My sons father and I were together for 3 years until 2 months ago.My son is now 15 months, we broke up because I was tired of him hurting me, he's always cheated on me, and recently I caught him on the next block with a girl who he's cheated on me with before, while me and his son were at home wondering where he was. He never worked and he never got along with my family, and I'm very close to my family. On holidays instead of spending time with me and my son and my family he would be with his friends. Now he text everyday to see how his sons doing, but that's all he does, he doesn't help me financial wise with him at all. he hardly comes and sees him nd he only lives 30 min. Away. He never ask if he could pick him up he waits for his mom to come get him in order to see him.. I know I'm dumb but I still love him, but I'm 100 % sure that I would never get back with him.Im a chain smoker bc idk how to get over him. Can anybody give me some advice on how to let go and get over him?
