Thanks so much everyone for your posts and feedback.
On the subject of a venue hire: our dance director said that he had approached the theatre in question many times before but only now, having seen our previous shows and videos, did they agree to let us use the stage. It is a professional theatre that picks and chooses their performers.
There are about 12 dancers and we couldn't possibly fill the whole theatre with friends and family. Still we sell out.
It is not fair to compare us to children's shows. If children look clumsy they are still adorable. If adult dancers look awkward on stage it is embarrassing to watch. Which is why we spend a year to prepare one show and our director is a complete nazi in terms of demanding absolute perfection in technique and performance.
I do not disappear all day on weekends. It is 1 or 2 evening classes a week. For the last show, we had about 6 weekend rehearsals of 3 hours each plus one fitting. That's it for the whole year. I appreciate that some dance companies require lots of time commitment but ours does not.
I don't demand that DH takes interest in dance - it's good enough of him to enable me to do it. And he has no problem complimenting me on my looks although I am surprised it got mentioned so often, it's really not about that.
It's about being a good dancer and when my dance director says that I do well I know he so telling the truth - so DH should be able to see it too. And his support would mean so much to me.
When last time I was at the theatre preparing for the evening show he phoned to complain that he was running late with DS's football practice. I listened while waiting for him to ask, how I was doing - the show time was approaching, we were all feeling nervous and excited. He didn't so I said "do you want to ask me how the things are here?" To which he replied "I am taking care of the children, do you want to ask how I am doing".
Maybe it is indeed too much to expect but when he is away for work I always ask how his presentation went, what the people are like at his conference, how he settled in the hotel, is the conference interesting. And he is keen to share and tell me everything. I think he would be offended if I showed no interest.
