Folk You dance too ?
This is something that I have actually talked to some of my GF about that I met through my salsa classes/events. I have dated a guy in the past who is a non-dancer and it was not fun for him to always sit and drink when the session that I took him to were full of dancers. So that was a down point for him. He also was too isolated and did not chat to many people, so I did feel bad about that aspect. The thing which really did bother him a lot was indeed how affectionate I was towards some of the dancers I knew that were regulars, and he definitely had an issue with that. I realised that he is not that kind of sociable guy, so he has an awful lot of questions in his mind about who, what, why, and how we met etc.
My ex said he doesn't mind meeting people or that I go to salsa. He say it in his mind, but until he saw how things happen, I bet he does mind. If I could handle things differently now, I would try to ask him to come, and I would also make sure that I only dance say around 30% of the time, and chit chat more. Or catch up with my friends until my partner is slowly eased into these kind of social settings. I would hope that he too get something out of it, and meeting my close close friends without pressure on him. So I would really try and choose venues that have both classes and social dancing, with a decent bar. So it can end up as if it a night out of drinking really.
To me, if I could, it is definitely one of those things that I would love a partner of mine to also get involved in, and that we can find dancing outings as a part of our lives together. Well, I hope.
It is actually not that easy to bring in a non-dancer to a full session where most people are indeed proficient dancers from years of experience. But I try to remember how it was for me in the beginning, and how it became a fun thing for me. I hope to be there to support them in finding that "spark" in dancing. As that was how it was for me in the beginning. I had good teachers and friends who made it fun for me.
Maybe it is worth taking him to classes first, where it may be less intense in the dancing, and more laidback.
