Sure.  Physical fitness is important for people of all ages.  Kids love to run around and play.  You don't necessarily need a gym for this but it will help them develop skills and interact with other kids.  They also usually have great equipment for them to play on as well.

Well... It depends on what kind of gym. Some offer children's care programs where they can interact with other kids and exercise while you exercise. But some are strictly for adults or mature teens.

Sweetheart... The best thing to do is to find someone else. Or think of the annoying things about him or her. I know you're going to say: "but there's  nothing wrong with this person". But think of the fact that they back-stabbed you, or remind yourself of their irritating quirks.
