There is no "should" be. You are where you are. There's no reason for you to go on a date with someone you don't think you'd be interested in. You don't have to go on a date this week, this month, or this year. I know, you want to have a companion, you want a partner. And I don't have any doubt that you will have that. But remember, you are special! And you can be picky! And there's no timetable that you have to stick to!
Reading your summary of your "selfishness"... it's pretty obvious that Dan was the selfish one, isn't it? You would have worked with him to reach his dreams. He didn't want to do it as a team. It wasn't you at all. When I don't get my way, I know my first reaction is to go find a bimbo to sleep with....
