Getting a divorce - is it ok?

I have done my absolute best in my marriage. I am not perfect by any means but I am at rock bottom and I cannot do this any longer.

My husband has repeatedly forced sex since the beginning of our relationship even when we were dating and I didn’t want to as I don’t feel comfortable with premarital sex. He has a porn addiction, has cheated, and repeatedly lies about looking at pornographic material. I will sometimes accidentally catch him or see it when I least expect it and my trust is broken. Every time I confront him, even calmly, he will shout and lie constantly and never asks for forgiveness. He claims to be Christian but I don’t see any evidence of that. He has been abusive and when he thinks I will leave for good, he acts nice and suddenly everything is fine.

I feel like I don’t know up from down. Is a divorce acceptable in this situation? Not one of our friends knows of his adultery, abuse, and other issues so I will probably have no support.
