Well, this is kind of complicated. If the people on the swim team are mean to you, I don't think you should rejoin it. And if the second guy that you like rejected you, you could still not give up, and try to impress him. Or you could play the dirty way, and steal guy from his girlfriend, if you really like him.

You do see the guys in places apart from the swim team, right?

Well, damn... Erm, if you think you can deal with the people being mean, rejoin the team... Be mean back if you can?

Or, you could try to go after guy .... By the sounds of it though, as much as I hate to say this, because I hate hearing it when someone tells me this. It might just be best if you move on. There's more guys out there, and you're not that old, so you'll find someone else...
