I want to leave my husband

We have a newborn and he constantly goes to his friends house for 6-7 hours and leaves me alone. We are both on maternity leave. But I feel like I’m doing this alone, taking care of our 7 week old cleaning cooking

I’ve talked to him time and time. He just tells me to chill. I don’t know what to do. I want him to move out. I rather him be gone than wonder when is he coming home

Update: thank you all. Saturday night here and he went out again. He asked if I wanted to go- I said no and I didn’t feel comfortable being around him knowing that we haven’t talked about how he has been making me feel. He said whatever and went to the party. I told him I want him gone by the following Friday. I am the breadwinner here and not worry about financially living on my own. I wish and pray though that his family is what he wants. 10 yrs together and I love him. But I can’t allow myself to be hurt by him anymore
