not really important but answers would help

He & you are not 2 anymore. Get on with your life and find a better BF.
If it helps any, soon your friend will probably see what you saw in him that made you break up with him and do the same.
Get over it.meaning?Direct your thoughts somewhere else and avoid having anything to do with him, and your friend.If at some future point you can deal with either of them it will "come naturally" to you, it will happen or it won't.Yes you could try talking to them but it's not that certain to do you any good, regardless of what it might achieve.L
There are (at least) two possibilities:
a) Your relationship is really over. He's trying to manipulate you by making you jealous. The worst that can happen to him is that he hurt you by compromising your friendship with the other girl. Whatta guy!
The only real option you have here is not playing his game. Inform him how his behavior makes you feel but that you are sticking to you decision. Tell him to the face at best, but pen and paper is OK too if you're afraight to loose your temper. Don't yell. Also talk to your friend. Warn her, tell her it's OK if wants to satisfy her sexual desires by being used by some random guy who might look good, but that she should be aware that this will make her look like a tramp to everyone else. She will know...
b) You didn't actually want the relationship to end. You just wanted to mess with his feelings. In this case, I don't really think I want to help you. Your heart deserves to burn. But anyhow, you should distance from this boy. Get some help and try again in some time. No good can come from this anymore.
You can ask them to try to cool it when you're around because it's making you uncomfortable, and if they're both reasonably courteous they should make some attempt in that direction... but in the end, you have no say in this matter. If you don't want him you have no claim on him, and if she does that's her problem and his, not yours. Presumably she knows he's on the rebound and is willing to take that chance.
Personally, I'm a firm believer that "relationships" come and go but that friendships can be forever. If he was worth having as a friend before you started dating, maybe he's still worth having as a friend... and if he wasn't, you probably shouldn't have been dating him.
best but hardest option - talk to him.Tell him the new relationship is making you uncomfortable, ask him to be considerate around you because you are still feeling sensitive about the break-up. If you can't say it to him, write it to him (pen and paper, not email, then he has to read it).That should solve things.However, if things get worse instead (he starts getting more lovey-dovey with your friend, especially when you turn up), then warn your friend that he may be dating her to wind you up.If she starts being more lovey-dovey to him when you are around, then you need to talk to her, reassure her that you are not going to try and steal him back, and you want to stay friends.After that, you're on your own (good luck).
