Because you are "me-minded". I was the same way for a long time until I learned to walk in love... JoyceMeyer.org
If you are jealous, you have a feeling you need to follow - what about him and his situation is making you jealous - jealousy is a feeling that lets you know what your emotions are lacking in your everyday relationships.
Yeah. Because some girls are trifiling and will do anything to make another person mad or jealous. Some just dont care about other peoples feelings and will use them and their emotions just to get revenge on someone else.
to get you jealous or his current girlfriend jealous or after to make you his rebound dont fall for it RUNNNNN!!!!!
You should leave him if he is flirting with other girls because he shows no interest in you. Apart from that he is just being friendly, don't get jealous.
If you still like that person then make her or him jealous by going out with there friend or something that will make them jealous. But if your just jealous and you dont like that person than just forget about it. this as been answered by Austin Bissonnette
Trust me, if you get jealous then you do still like him even though you dont want to admit it.
Dont get angry. Get even. First, make sure that he actually is flirting with another girl, and then start flirting with another boy and make sure that it gets back to him. If he confronts you about it then say, "Oh sorry, I thought that was OK considering that was exactly what you were doing with (other girls name) " He will have no choice than to explain everything to you. Simples.
you want to know why because they get jealous and dont want you dating another person
I also dont know,better luck next time
ask her to stop flirting with you if you dont like it, or if you like it then tell her so.
if he doesn't like you then he won't get jealous.
You can never actually be sure, but if there is flirting, staring, and defendence then you know he is true!!!! So dont worry girl, he's there when you need someone to cry on, and to be happy on =). Dont be scared to ask questions either or spread feelings, he is there for yoooooou!!!
