Tell him you only are interested in being with him... Or if he is still too jealous, dump him.
If you are trustworthy and they can't trust you, run away. I've been there. It doesn't get better.
well since there really isn't enough info, taser him, tie him to a chair and leave him in a gay bar
Replace him. He's a cheater.
Explain that jealousy can be the reason for a breakup and not another person.
Lose the boy and get an emotionally secure MAN.
umm, comfort him ? Unless he is jealous all the time.
