Divorce

My husband decides he isnt happy being married to me because he said he wanted to be single. And he tells me that everyone pushed us to get married when I was 4 or 5 months pregnant with our son. He wanted to get married he said oh we can get married and do right by our family but now he jus wants to get a divorce. And I don't want that. He jus doesn't want to be with me. I cook, clean, taking care of our son while he works and he still wants a divorce? I just give up on everything. I never thought this would happen. Its jus to hurtful now. Our son is fixing to be 5 years old in August and I dont want to put him through any of this. I want the marriage to last but idk anymore.
