You can’t allow him to see the kids, unless supervised. He is the one with addiction not you, and you with a clear head need to make right decision here. God forbid if something happens to the kids you wouldn’t be able to forgive yourself.
He needs to change if he wants to see his kids it’s plain and simple. Your kids are innocent here. They don’t deserve to see their dad under the influence of substance abuse. You don’t want your kids to think it’s ok to abuse any substance either.
If I was you (and I am you) with similar story I left he is not allowed to see them until he cleans himself up. And from looks of it he has no intentions of doing it. Coke and his gf is more important their his kids.
He calls every once in a while saying he will kill him self but he won’t. addicts are too selfish to end their life. It’s just their way to guild you into helping them.
You didn’t get married and have kids to be abused and for your kids to be abused and lied to and manipulated.
He is the only one that can stop his addiction and actions HE IS GROWN ADULT. When he cleans up your kids will be there to welcome their dad back.
Good luck!!’
