My ex of several years was like this. Still makes my gall rise to think how many years I spent appeasing him until he got what he wanted. A miserable me.
Your DH sounds like him, in behav iour. Its not that he doesn't want you near any single men, OP. Its because he wants to disrupt something you love and enjoy doing. Like you I have a dance background, I performed professionally although I wasnt doing that so much by the time we met. My ex knew this and was absolutely fine with it...for a while.
Further into the relationship he showed his true colours. Would find excuses to be sulky days before I had a workshop, or show. When I wanted to go to dance classes he would pick arguments and yes I got the cold shoulder treatment. I didn't make the mistake of thinking he was oh so worried that Id jump or men, or they'd jump on me. No...it was solely that he wanted to prevent me doing something I loved.
Except - his plan to have a miserable me with no outside stimulating interests didn't work as I eventually dumped him. It wasn't a pleasant experience..he went ballistic. It was worth it though. Privately in my mind I named him The Dementor as he sucked the joy out of everything I did. What a relief to get rid..when before then Id thought I could never live without him.
Not saying you should dump your DH but I doubt you will be able to live with that level of meanminded control. When you stop going Salsa it will be something else...
My OH now isn't greatly into dancing. & I don't perform professionally anymore. But we go out dancing together, he compromises because he knows I love to dance. He doesn't bat an eyelid when I go off to classes by myself either. We are happy. I look back and shudder to think what my life would have been like if Id stayed wasted even more years of this 1 life with my ex..
Hope you manage to sort things out and it doesn't involve stopping what you are doing to suit your DH.
