I want to leave my husband

He doesn’t help do anything. I found texts in phone to other girls. If I ask him for anything he acts like it’s a chore. The only thing is he cannot take care of this baby on the weekends he would be allowed to and he would have to move in with his mom. She had 8 Yorkies all in the house. They never go outside. They wear diapers and have pee pads. I do not want my baby there 🤢Every time the baby cries he wants to feed him. Even if it’s only been an hour since his last feeding. He literally could not handle this. I have no idea what to do.
