I would also encourage you to get out of the relationship.

I totally get you in how you feel about the constant threesome pressure. They have zero idea what it does to us psychologically it just makes things worse. Made me feel unworthy, unloved for just who I was, not good enough, like an object rather than a woman. It festers and grows psychologically.

I got to the point in my life that I just made myself fat. Closed off the idea of allowing in any more relationships, so making myself unattractive, I suppose finally became a self-defense mechanism. I don'twant to swe you end up going as far as I did. If he is abusing you, be good to yourself and get out of the relationship , give yourself time to heal and then when you are ready, open yourself up to finding the right man for you.
