Well... Good question. :P What I could do is get another girlfriend and be all lovey dovey with them or fake a relationship by writing someones elses name on your hand and saying you have this smokin hot girlfriend... Lol. But yeah that's all I can think of. Hope this helps... Bye
You answered it yourself. He got with the other girl to make you jealous. It doesn't make a whole lot of sense.
Most likely
They're obviously trying to make the other girl jealous.
A girl who is trying to make you jealous will only flirt with another guy in front of you. Anything more than just flirting means she's not doing it just to make you jealous.
Lurn how to write a sentence?! "how do you make a girl jealous of me?" not what you have put.
He either is trying to make you jealous or he doesn't want you to be jealous
Go on with life... or make her jealous and date another girl.
Try playing 'hard to get' or make her jealous by pretending interest in another girl.
Beauty
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.
Be better than she is by acting like you dont care
Its about a girl he dates. And he sees her with another guy, and he tries to make her jealous by being with another girl and he wants to unfriend her.
