Begging....

I broke it off with my ex (of 4 years) in mid November. He begs every single day to come back home. His main points are that we've spent so much time together, we have a son, and that we love each other. I'm trying to get him to understand that those aren't good enough reasons to reconcile. I ended the relationship because 1) He wasn't attentive to the household 2) He was financially irresponsible 3) He was too insecure 4) He lied a lot *Most times he had no idea I knew he lied* 5) He cheated *3 different females texting and sending freaky pics...one was 2 days after I miscarried for the 2nd time* 6) When I miscarried the 1st time, he went to work while I was at the ER dealing with the trauma. 7) After I gave birth to our son, I had postpartum depression so bad. He refused to go to the doctor with me in order to understand what was happening and threatened to leave me. 8) His priorities: Friends, weed, and sex. 9) He was physically and mentally abusive at times. He told me he wants to propose. lol. He thinks I should just leave everything in the past and give him another chance. He doesn't understand his mistakes weren't minor. It wasn't little stuff like coming home late or a few small lies here and there. My pain is deep.
