Dumb him. More guys need to be laid back and care free.
I say most guys that do this are insecure
I would honestly have told him to do one by now.
Anyway! As it doesn't sound like you want to do that, you need to have a serious talk with him. If you've already had one, have a more serious one. It's often said that once a person has cheated (especially if they managed to keep it secret for a while) they get incredibly paranoid and overbearing because they fear the same thing will happen to them and they might not know about it for a while either.
Just put your foot down and tell him you are going to your friend's party because it's her 18th and it's a big birthday and you need some quality time with your friends. Tell him you are going skydiving because it's something you really want to do. Just tell him how overbearing he's being and that you're 100% trust worthy and if he doesn't realise this he's going to really push you away.
Just make him realise that you're not going to let him dictate what you can and can't do with regards to your friends etc.

Break up with him! sounds like he still feels guilty about cheating on you and is scared that you will cheat.
even though yyou love him trust is a massive issue in a relationship and its your life! you should do what you want, within reason, and he should fit around and be ok with it.
Dump him, he sounds like an ass.
Unless you talk to him and try to solve the problem now, it will only get worse.
He is in control of your life and preventing you doing the things you want to do. This is not a relationship.
You shouldn't have to ask his permission to do anything.
If I were you, I'd just do what you want to. If he doesn't like it - too bad. You can't let him control everything in your life.
I think you should have got out of this relationship 4 years ago! I can't believe you've let him control you for 4 years!! How could you deal with it for so long and why is it suddenly an issue?? Sorry but I would dump him. xxx
He wont let you go sky diving because he's afraid a man will be strapped to your back? Sounds like a control freak.
What do your friends and parents say about it?
