Overwhelmed.. venting

Me

Many of you know I'm a single mom. Thankfully I get a lot of help from my parents and older sister which I'm more than grateful for! But right now I'm overwhelmed. My ex husband is giving hell about this divorce. He'll tell me one thing and we'll agree on something then he'll talk to his mother and completely change his mind. He's basically being a puppet of everything she tells him. Then my mom is mad at me for even trying to go through with divorce because it's "ungodly" and my sister is upset because according to her I'm going to let him off to easily. I would like to be free from my ex and no I don't want to sue him for all he's worth. I'd rather have him out of me and my son's life completely. He only sees his son about once a month because he always calls off visits and my son doesn't even recognize him when he shows. Also the last two visits my ex slept through because apparently he's on night shift "and visits are hard on him" then he insist on sending a $60 per week "child support" but when I tried to explain how it's not very helpful, he threw a fit about how I'm not appreciative of him and his efforts. Ha also keeps saying he wants legal custody and is going to fight for it. he acts like he wants all the benefit of having a child without any of the work and responsibilities. I really want to move forward and finish my degree, Get a place of my own and give the best to my son that I possibly can! But I'm afraid I'm going to get stuck where I am for a while because of my ex 😭
