Child Sharing Agreement

Ive never been through this and im a bit confused. My daughters dad has been working in another state since April, hasn’t seen her since. We broke up a couple months ago, I was dancing at a quinceañera (sweet 15) and to him that’s cheating apparently. I didn’t discuss it because he’s always done the same whenever in not there but whatever. Ever since we broke up he has drinking EVERY Saturday / Sunday drunk. He has always been a drinker socially like any other but not like an addiction except now that’s every weekend every time he’s drunk he calls at 2-3 am and starts to fight or insults. When we were together we agreed that he wasn’t going to be returning to Mexico for 2-4 years that he was finally going to be stable and stay with his daughter for good. (Bc of work he had to leave) Now all of the sudden he says he might go and if he does that he’s taking our 3 almost 4 year old with him. That is a quick no obviously. Because in mexico in December there are nothing but party’s that he will most likely be attending and more drinking with his friends. Whenever we would go he would always want to go out with his friends to drink or go to parties and now that he’s single he is going to able to enjoy what he always wanted, and not only that he already has another girlfriend so quick and he’s going to be with her and not with our daughter. She’s going to be in the care of her grandma everyday. He’s very irresponsible and immature.

What he said that made me mad was “ok if not December because of the parties and all that ill just get her January when there’s nothing going on”. The fact that he says he loves his child and prefers party’s and his girlfriend first and then see his child. Is so ridiculous. Yes he’s a great dad and help out with everything but ever since the split it feels like he broke up with her too. He doesn’t call her like before, he thinks 100$ is enough for the whole month for child care. Doesn’t ask for pictures of her anymore. He’s never bought her presents and now he’s trying to show off by telling everyone that he bought her clothes and a tablet over there where he’s working. Instead of calling me for her sizes he called my mom.

I don’t know what to do, I don’t want to be the bad person in denying him to see his daughter but I also don’t want to send my daughter to mexico with him.
