The answer to your question is highly preferential and depends on many different factors.
In general, boys are looking for girls that they can relate to, love, have fun with and be comfortable around. Girls that are unique with a bit of edge tend to attract boys more than "mainstream" girls.
Acting confident - not arrogant - gives boys the impression that you are sure of yourself and can make competent decisions. Some guys find this attractive.
Particularly in teenage relationships, it is vital to have an element of fun. Often, teenage boys enjoy a "flirtatious" and "sexual" element in the relationship. If you act "fun", it will make you more appealing to a man.
Who told you that you need one?
If you are trying to talk to a girl and she keeps saying, "Bye, I have a boyfriend," she probably isn't interested. She is letting you know that she doesn't want to talk to you. There's other girls out there.
The way to look at is if your boyfriend loves u he will belive u. That other girl is probably just trying to get with your boyfriend .
She probably feels bad after what she did to you. Even if you now hate her after what she did to you she feels the same way as he was her boyfriend too
Sort of ....... She keeps breaking up and getting together with him over and over again.....
You be patient and you wait, because they are not getting married
you might be getting cheated on ):
There are no secrets to getting a girlfriend. Girls want a boyfriend that is kind to them and does not lie. Be a friend first and treat a girl the right way.
If the girl you like has a boyfriend and the boyfriend tries to fight you, it is important to prioritize your safety. It is best to avoid physical confrontation and try to defuse the situation peacefully. Communicate your feelings to the girl and respect her decision to be with her boyfriend.
if she keeps asking you about relationship for one, kinda like a wing man, and 2nd when they hang out with you more than they do the boyfriend. those are probably to ways of finding out
she wants to see if you are worth the smooch
either he wants something to remember her by or he still got feeling for her
a way to know if he likes another girl is if he keeps looking at her and smiling also if he talks about her with his friends.
