Can full custody be granted if the common law partner is just an AH?
We were all better off when my common law husband was smoking weed, or, throwing up blood in the bathroom (suffered the cannabinoid hyperemesis syndrome occasionally). He stopped smoking weed, since Easter, and now he just yells at us, fights with me. Even when I yell at him to just smoke and be calm, or just smoke and risk it, and least then he won't be a complete and utter AH to me, our 4 y.o. son, and our 15 month old daughter.
This is the first time with him being sober and all I want is for him to pick up another habit if it would have him calm the fuck down. This past Saturday morning is but one example:
I was in our basement filling some paperwork out, he was getting up with our kids until I was done as he was still asleep when I went downstairs. Our 15 month old wakes up, it is 8am. He does get her up but she needs a bottle (I always have the bottle ready, he didn't) and as she began to cry, he got frustrated and she kept crying amd he yells at her to "Shut The Fuck Up!!!!!!" This all took place in around 5 minutes. He couldn't keep self control of anger for 5 minutes before blowing up. When I got to tell him to go in another room, he yelled at me he's not a morning person. Nobody is. Nobody wants to jump into work the second they wake up, it is what parents do though.
I already feel I am doing this alone, and, I am losing nothing when I walk away from him. I anticipate the day with happiness. We are in constant "walk on eggshells" mode since Easter in particular, it is just worse since Easter.
We haven't been physically abused. But, we are yelled at all the time. I do have some recorded. Is full custody possible with that? I was told no physical abuse and yelling but not name calling isn't enough for full custody, especially since he told me he will fight me.
He refuses therapy. What are my options to leave?
EDIT: Thank you to everyone for your comments, I am reading all of them, but only may respond to a few.
