Should I stay or should I go?

My man annoys me. He thinks the only bill he has to pay is the phone bill. He claims he will get a job but hasn’t got a job yet. I’m not working at the moment so am I contradicting the situation here? He works on cars which isn’t enough money. I have income enough to pay my own bills and do my part as a parent. I pay the rent and for the washer and dryer. I provide the food he gives me rides I don’t have transportation at the moment but I am a business owner. He smokes cigarettes and they smell horrible and I hate to complain so much but stuff he does annoys me. He comes in get in the bed with his street clothes on and don’t shower until I’m nearly tired and sleepy. I feel like he uses me for a place to stay and by bills not being so high he’s content with just paying the phone bill. I believe that he has bad home training he lives like a bum he’s hunky and cluttered while I’m neat and clean I’ve had talks with him about this he keeps getting in our bed with dirty clothes. He doesn’t take care of his kids call them and check on them unless I request and demand that he does. He had a bad odor I’m not turned on by him anymore. Yesterday he said I was set in my ways because I cook and clean prepare all four of our plates and I feel the least he could do is wash the dishes. I have a 7 year old and a 3 year old so I’m not able to make it a chore for them just yet. But I feel like I’m doing everything and he’s doing nothing I got back with him because he said he had a job. Well Monday came and he never went to it. His concerns on not getting a job is because child support. Am I wrong for wanting him to get a job and I’m not working? What should I do? I don’t want to make a wrong decision in leaving because he has potential he is good to me and the kids but I feel like we just playing house for the sake of the kids. Which aren’t his! I kind of need him in a way but then again I don’t because I pay for everything except the phone bill. He isn’t on my lease because he’s a felon and I’m on hounding so if they find out he’s living with me I can lose it all. I need advice on what I should do.... thanks for listening
