These are serious allegations, what is your evidence?

Right now, if the police were to be involved, nothing would happen because this is a he said / she said situation.

Gather evidence. keep your texts. write down what you have posted here. Does he act this way with others? Does he post his thoughts online? Has anyone else witnessed his actions? Have you told other people what he has done?

Don't go to his place, don't invite him into your's. Never, ever , be alone with him again. Carry your cell phone at all times. Change your locks.

Being your godfather is meaningless. You are an adult. He has no legal authority/ standing over you. You do not have to have anything to do with him.

Make contact with a women's shelter. Not only will they give you advice, they can also be on standby if things get hostile.

Finally.......Where is your husband in all this?
