I'm back and my heart is broken

[overcom]

Hi guys. I'm glad your all here to support me and give me advice. I'm more stronger then I was a few weeks ago. Things are completely different with me. I have completely detached from him, I am more confident, I have my set goals and boundaries. It took a while to learn but I am trying so hard. Not to win him back but to make me priority and my kids.
Here is something that happened and bugs me and I don't know if I shoukd say anything or just drop it. He was supposed to watch the kids yesterday and I left at 8 to work he fell asleep on the sofa with the kids awake. Around 1030 my mom came and knocked on the window and he opened the door and went back on the couch. Within mins he was snoring again. My mom was shocked the whole house was a mess. The kids had terrorized the house. They were eating candy cause they were hungry and this a$$ hole is sleeping not giving a [censored] about the kids. My mom cleaned up washed the dishes took the trash out and he was still sleeping. She went in his ear and said I'm taking the kids he opened his eyes and went back to sleep. At 430 my mom dropped the kids off at the restaurant by his mom and she brought them here. I was pissed!!!!!!!!He was trying to give me [censored] attitude why is your mom picking up the kids. When I move out and anyone comes over I'll put them down and I said excuse me. That's my mother your talking about. She's the ONLY ONE EVER TO HELP. NO ONE HELPS LIKE HER. SO WATCH WHAT YOU SAY. If it wasn't for her who knows what would have happened.(this was veterans day). Yesterday he took his gf shooting range, didn't once call to see how the kids were, didn't show up, nothing. At 130am he calls to ask about the kids. I'm so beyond mad. What the hell is wrong with him.
