Dead beat dad

So my now ex walked out for good. He said he rather be a dead beat father then have too deal with raising a kid with me...lol

He acts like I’m the bad one.. he buys alcohol and weed instead of stuff for his daughter, he chooses to go get drunk and high instead of spending time with his daughter... all I asked of him was if he was gonna watch the baby that he be sober and not high... so harsh right? 😂 I’ve tried going with him to AA meetings but he refuses to go, he refuses the help. He refuses to believe he has a problem, but he does and I’ve tried everything to get him some help. Honestly it’s not fair to my daughter. He’s gone to to work drunk multiple times but yet still denies he has a problem. Now he’s jobless, sleeping on his friends floor, paying his friends rent since they don’t even work, and drinking and smoking all day....when he could be seeing his daughter grow oh and helping out with her. So I’ll let him be some dead beat and raise my daughter and son, and when she’s older I hope she appreciates what I’ve done
