This happend to me, i became depressed, i didnt understand why she would do such a thing. But i had to move on, obviously she doesn't care about your feelings, and you can't blame the guy because he probly didnt know you liked him.
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
because the person you are dating is with another girl and is cheating on you
Jealousy is a worthless emotion. If the person you are dating gets jealous, then it may not be a healthy relationship.
you want to know why because they get jealous and dont want you dating another person
Their friend may have already liked you or is jealous
Why is this a problem for you? Is your cousin a bad person? Is your friend a bad person? If the problem isn't a safety issue then you should wish your cousin and best friend a long and happy relationship. You may want to ask yourself if you're just jealous of the relationship they share.
Just don't talk about your boy friend around that person
This happened to me too! And it depends on the kind of person your friend is. Is she the jealous type the? The gullible type? Does she not pay attention to what's going on around her? What you should do is make her jealous by getting a new friend if she is the jealous type. If she ignores you then find that other person a new friend. They'll find a new friend and you get your old friend! Pray to God for guidance everyday I will be praying for you!
I would say you cannot. If they are your friend with benefits and you have the other person has absolutely no other interest in you but sex, I don't see it possible.
because maybe the person who is asking might be jealous or just wants to be a part of it or just plain nosy
Well, sometimes just because you love them, and they don't love you, the more and more you think about the person, the more you love him/her and get jealous with whoever he/she's dating. Sometimes you feel like crying because you're not the one he/she' dating.....
tell your best friend and make them all jealous and then love yourself to pieces!
