I disagree with most here about the problem being tren. With tren he'd more likely be paranoid, accusing you of being unfaithful, controlling, and quick to rage. His attitude sounds more like he just wants to keep you on the side as a spare tire while he gets his rocks off everywhere he can. Testosterone and certain other drugs make us extremely horny, and some ancillary drugs like mirapex/pramipexole make people do really strange compulsive things like gambling, homosexual sex, and cross-dressing to name but a few. It's not fair to you, move on. You are not his mom, sister, or his keeper. I don't know how old you are but the older you get the less bullshit like this you will put up with. Good luck.
