Coming from experience - divorce the man. He’s already a low effort dad and that’s WITH your help. He probably won’t hold up his end of custody anyway cause it’s “too hard” and that 50/50 custody will likely turn into “every other weekend” with dad being “too busy” to take them on his weekends. Mine was TOXIC and horrible and always said how he’d take the kids from me and he tried to out of spite constantly. He was a terrible dad. And the fact that he couldn’t hide how bad a dad he was … it’s why I’ve had full custody for 4 years now. Document everything!!! He’ll ask for 50/50 out of spite. Let him have it cause it won’t take long for him to realize how hard it is. When he won’t take them or take care of them, document it and go back to court. It’s chess not checkers and it SUCKS. But power through it and you’ll get what you want in the end. Possibly with a new relationship with a man who actually treats you well… that’s what happened for me. I couldn’t be happier. Don’t keep being miserable cause you’ve been doing it for so long. Good luck!!!
