Financial and Marital problems

"Dear Housewife,

Ok, I don't know where to start.
My husband and I have been together for 5 years now. We got married a year and a half ago, and had a baby a year ago.
We have filed bankruptcy but we are still having financial problems because he is not working full time hours. They send him home early a lot. He keeps saying he is going to look into getting a part time bouncing job at a bar, but I'm not too crazy about that.
Another thing is that he goes and hangs out at a friends house about once a month but does not come home until 3, 4, or 5 in the morning. He says he falls a sleep there.
I don't care if they go out or stay there, but he does not give me the respect to call or text me on how late he will be.
I will wake up in the middle of the night worrying about him. I text him, no answer, I call him, no answer. Last night he didn't get home until 5:15 a.m. and I'm so upset about it.
If I go out with a friend, I am usually home by midnight.
Should I be worried, should I kick him out even though I really don't want to split up the family?
He is not attempting to get another job to make more money, I work OT if I can, and I have applied for several part time jobs. I'm tired of doing it all. I'm just so confused on what I should do. He also got upset that I was going to be gone on Saturday because I had the chance to work some OT."
