What would you do

So my long time boyfriend and child father who I live with stays out all night like 4am and I have his location so I know where he is but still he will stay out all night go to bars and clubs and also stay at his moms house for 2-3 days leaving me with the kids. No calls or anything just updates through text. He will use the excuse of he doesn’t have a car so that’s why his hours are late etc. but I’m always alone doing everything for everybody and nothing for myself and I’m so tired of saying it that I honestly might not even say anything when he walks in again in the middle of the night I don’t have any arguing left in me I just want to be respected
