hello ladies!

so here is a quick run down. My AH has been abusive when drunk. We have an 8 year old daughter and a 4 year old son.  Whenever I have asked my husband to get out of the house he always responded with “it’s my house. If you don’t like how you’re treated then you get out! I’m not going anywhere”... so for the last 8 years I’ve tried to make it work. Only because I’ve never wanted to go thru a custody battle with him. He is a drunk loser but he will fight tooth and nail to make me miserable. So I finally left 5 weeks ago. As soon as I left he started posting on social media’s about his girlfriend. And when I looked her up, she was immediately posting pictures of her daughter at the house I just moved out of! He bullied me out of the house and moved her in immediately. He has blown our kids off (which I am happy about), he has only seen our kids three times over the last 5 weeks. Lawyers have been telling me that I have to let him see our kids when he wants to in order to prove that I would make a good residential parent. So yesterday he tells me how he has been seeing this girl and she is living with him and he wants to introduce them to our kids tomorrow. I asked him to wait because it’s so soon I know it is going to devastate my daughter. But he is insisting. He said “they’re going to love Melissa and her daughter! She’s a great kid! We will be a happy family together”... I’m like uh okay have fun with him Melissa lol don’t come crying to me when he threatens your life! AND now he filed for divorce seeking residential parent! Has anyone gone thru divorce with a stubborn AH? Is there any chance he will get it? He said “you’re an unfit mother! You’re living at your sisters out of one bedroom!”.... I said “uh because I had to get out of that house because my husband is a violent alcoholic! This is just a temporary living situation because you haven’t given me a penny!” It’s all so frustrating. He only filed for residential because I filed for child support. He thinks if he is residential I will have to pay him child support. But I seriously doubt with his substance abuse and background I don’t think he could get residential? I just worry because I feel like even the simplest things go bad for me. If they give my kids to that monster It’ll break me and my kids hearts. From day one I am the one that takes care of them, makes their food, preps my daughters backpack and lunch for school, says prayers and tucks them in at night. And the thought of his new girlfriend skank playing house IN MY HOUSE infuriates me. It’s absurd that she has that little respect for herself to move into my house after my husband basically bullied me out, my side of the bed wasn’t even cold yet and she’s moving her crap in and her kid is playing with my kids toys. Ugh so frustrating. If anyone has any divorce advice it would be greatly appreciated!!
