I want to ask my husband for a divorce.
Why do you want to ask your husband for a divorce?
He's been hitting me and I can't deal with it anymore.
You should end your marriage if your husband is abusive to you. You can try therapy if he's willing to go and try it. If it doesn't work, make sure you think of yourself and your safety.
I'm planning to get a lawyer, we won't be able to work out our differences.
If can't repair your marriage then you should end it. You should not be in an abusive marriage with someone that's not willing to change and improve himself.
