To be fully honest it depends on the girl; but overall most girls think it's pretty cute when a guy is jealous of another guy, but too much can be over-powering. So do it every once in a while to show that you care about her, but don't do it so much that it annoys her because you won't let her hang out with any other guys. Glad to see that you want to impress a girl and hope this answer helps!(:
You are being possessive and need to give him space. If you don't do this he won't be a boyfriend for long. Do you have girlfriends? Do you like to do things with them? If he told you what to do with your girlfriends how would you feel? You wouldn't like it. The same with him.
Girls have boyfriends because boys can easily get boyfriends just like how girls can get girlfriends so girls get boyfriends to prevent boys from getting boyfriends and girls from getting girlfriends.
Sometimes they blackmail there girlfriends to stay with themor they like bashing there girlfriends up.
Jealousy
For the make up sex.
because they probably think that the person they did it with like pressured them or something, so they don't blame the bf/gf for doing it ?! its stupid
I know it will seem weird to men...but girls call there friends girlfriends because they've been there like there boyfriends have been there for them...also because they kinda are like girlfriends to them....yes i know guys don't call there good friends boyfriends..but they don't want to seem gay....thats why.
Always be yourself, but definitely do not be rude. It sounds silly but manners matter. if the girl doesn't like you as you then she doesn't deserve you!!
We like to girlfriends and boyfriends because it feels good to be loved.
The previous boyfriend/girlfriend that they had before, that theyve broken up with
They are afraid you will compare how good in bed they are to these boyfriends and scared that they will not be the best - men like to feel they are the best!
Don't do anythign because you will have or had boyfriends/ or girlfriends that they won't like and you pray that they would not do anything.
