You have to do the same cause that way he will want you back and be sorry cause girls win all the time.
It's not a bad thing. Honestly most girls get jealous when there boyfriend is talking to another girl. But you shouldn't worry about it.
Live with it or you will lose him

Calm down and relax. I think.
it means that your unsure of your relationship with the guy, and that you really like your boyfriend. You get easily jealous if there would be a girl trying to steal your boyfriend.
When he is your EX-boyfriend and you are over the relationship. Let your heart be your guide.
She might be scared that she will loose him.
Yes and it is a perfectly normal reaction to be jealous. This is a good sign; it means that your boyfriend is good looking to not only you but your friend. The most important thing is that he is yours, you have him and she doesn't so be happy that your boyfriend is fanciable.
Find a guy for yourself; there are many out there, and you just need to get to know them.
Use reverse psychology. Get another boyfriend to make your ex jealous. And if you can't get another guy, ignore it. Act COMPLETELY oblivious to his new relationship.
she wants you to still be in love with her, even if she has a boyfriend.
I would say no... but it depends how jealous he is? why is he jealous?
