I'm stuck

I think I'm in an abusive relationship, and it's not good because he has bad depression. He doesn't want to hurt me, I know he loves me, but when he gets depressed he gets really mean, and threatens to hurt himself and kill himself. He has a huge fetish for me to fuck other guys, and begs me too, but if I do something like it, like satori sent him vids of me at the club, first time going, and grinding on a guy. He acted like he loved it, only to tell me later it was a "test" and I failed and I don't actually love him, he continuously begged me to do it. The next day he apologized, saying I did nothing wrong, that I was the best girlfriend, and then asked if I could hit the guy up and fuck him. To which I keep saying "maybe" or "no" and he keeps pushing.
