Fed up

Moved into my own flat with my son and allowed my partner/baby dad to move in with us, and honestly it's been a nightmare, he literally does nothing apart from play games and I'm left to deal with our son 24/7, he doesn't even pay any bills or do any food shopping, I'm literally left with doing everything and atm our son is super clingy so I literally have to carry him around while I'm cooking, cleaning, doing laundry, anything I do I have to carry our son around with me because he's too busy playing games and flat out refuses to take him, he eats all the food so there's literally nothing for me to eat so I've gone almost a week now without eating one single bite of food because once the food is all gone I've got no money to buy more because its all already gone on the food shop and bills, I've tried kicking him out but he refuses to leave, I'm starting to find it so hard to keep on top of stuff and look after a baby while being so hungry at the same time, don't even have any friends or family to talk about it all
