“I am tired if being married to him”

I am a married mom of a 17 month old. My husband is 22 years older than me. (Yes, judge if you want. *rolls eyes)  In the beginning of our relationship, he lied about his past. I had to figure out his back story by myself.

Then he finally admitted everything. Like the fact that he owes child support arrears. I am the only one who works. I took out $100 so him and my son could eat for the week. Come to find out, he gradually took out the only other $100 left in the account. He claims he spent it just on food. But I know it’s a lie. Anyway, the whole situation is a long story. But I am tired if being married to him. I just don’t know where to turn to. I have no family or friends. I’m scared to go to a shelter because I don’t trust anyone watching my child. Any suggestions?
