General aggression towards the new partner, aggression towards yourself.
jealous
She's most likely jealous of the girl and likes the boy.
yes
I have situation like this and I know the answer. If a boy likes you he will be looking at you a lot. Also he will try to make you jealous by being with other girl all the time. All you have to do is to keep calm! Trust me
If he is making you jealous just ask him out your self if you know he is not going to ask you out!!
If he knows you hate her, it could be to make you jealous. If he doesn't know you hate her, probably he doesn't know how horrible she is.
Getting a boy jealous is not right. If you do try to make him jealous then your not being yourself because if he doesn't like you before you tried than he is not the right guy.
He is immature
be jealous and then try to be friends with that boy until you get close and then you can make her jealous.
That means he likes you and is jealous.
Make him dead jealous(kiss another boy)
