Does he want to be here?

I have been in a serious relationship for 4yrs. We have a 3yr old son and it seems like I am the one to take care of our child ALONE. Since he was born I am the one to do everything, yea his father has been there to give a bath or two and took him to the park when he is mad at me. Every night I come home from work he leaves right after dinner. He says he hates staying home, I have agreed to go out for drives with him and to stores, but I cannot afford to put gas in my car everyday and I sure the heck cannot afford to spend money at the store every night. He suggests to go with him every night, but he hangs out at warehouses with friends and does things where I prefer not to bring my son, (NO nothing illegal), the places he goes to are very dirty and I do not like our son getting into that stuff. I cannot handle this anymore, I feel like if he is not around to help me I might as well do it on my own as a single parent. My biggest complaint is that he is never home, and we argue about it all the time, he always says I will try to stay home, but you piss me off so I want to leave. How he gets mad is he aggervates me in certain ways to where I yell at him and tell him to go away. There are times I am so used to him not being around, when he is around I want him to leave. What do I do??? Tell him it's over or try again??? for the 100th time? Tweet
