I've been single for a number of years now and have been happy with it just being me and my 2 DC. However I attend somewhere where I have met someone, he's nice and as far as I know he's single too. Now I really want to ask him out, but he's part of the organisation of where I attend so I don't know if there any kind of rules around this and if he says no I don't think I could go back. What can I do? Do I just go for it and ask him out or do I leave it and see if he asks me?
