My husband embarrasses by trashing me and our marriage on Facebook. I have only been married a few short months and on a few different occasions he has put on his Facebook that he made a mistake marrying me. Another was that you don't know someone until you live with them. I have said we need counseling and he has ignored it. He also avoids discussing problems. I feel emotionally abused and I can't trust him to not hurt me. What do I do. I have moved my things out but am wondering if I should just file for divorce?

First if the home is owned, you perhaps errored in moving out, but anyway. Yes you hire an attorney to protect yourself

Yes, you file for divorce and you use cruel and inhuman treatment (if it's allowed in your area) as the grounds. Keep in mind that you have deserted the marriage and he has grounds to divorce you.
