If you want your ex-boyfriend to be jealous you have to flirt with someone he knows right in front of him. To make your ex-boyfriend to want you back is start being more sexual and also flirt with him a lot of times.
Tell him you want him back and if he doesn't want you after that then find someone else.
sexual seduction
Just be honest with him & tell him how you feel if you want to get back together.Ask him if he likes you tell him you want to get back together & be patient with him.Or you could just bang him.
If he founds out that you are with another guy and gives you call .He then tell you the person is bad and you must not go out with him and start saying bad about him continuously and compares his n your relationship.He is jealous.
He could want you to come back or he is sad and being stupid.
Keep things casual and simple.
It is unfortunate that you were cheated on and then he left you but it may be the best for everyone at this time if you parted ways as it seems he is not ready for a committed relationship.
just do it, if u both want 2 try it again, then u should. there is no harm in going back out with ur ex, just don't be disappointed if it doesn't fully work out.
If he won't talk to you, you should leave him alone. He doesn't owe you anything. You can't make someone like you.
Frankly, why would you want him too - he is your ex for a reason and he has been sleeping with others - I would scrap that and move on!!!
