no you cant
If you easily get jealous when your girlfriend talks to or befriends other boys, you can stop that by being positive always, and trusting your girlfriend.
Calm down, breathe deeply, smile. Being jealous is normal. Acting jealous isn't a good look.
If you dont know who the guy is then you should find out before being jealous. But if you do know the guy then you should just go have a long talk with your girlfriend because if you are jealous, your girlfriend might just break up with you.
make him like you better
I think being insecure and jealous on your part does not help your relationship or your studies. In may be in your best interest to be single for the time being to sort out your feelings, gain your independence/confidence, and focus on your studies, goals and future.
Feel good about it. He's with you, so don't feel insecure about other people thinking that your boyfriend is hot. I'm a guy that's fairly good looking and I have a hot girlfriend who gets hit on all the time. I don't make a big deal about it. I may get a bit jealous but I quickly feel good that my girlfriend is a hot commodity and that she's with me. Being insecure does not help. Just take it as a compliment and don't let it interfere with your relationship.
If you feel that your girlfriend spending time with her brother is a problem to the point of you being jealous of that, then my friend the problem is not theres but yours, and if there is something really wrong, then just get another girlfriend, if theres something there that's funny then you have no business being in something bad. Good luck. SELAH!!!
Because the boy loves the girl so much, he can do anything for her girlfriend he loves her girlfriend so much! Or, it could be because some see their girlfriend's either as possessions or as being unable to control their emotions and prevent being seduced by other men.
Ingore both of them and try moving on if she is being mean to you then she is jealous!
If you were completely secure with whatever it is that is bothering you, you wouldn't be jealous at all! Because you'd know everything would turn out in your favor. Thus, I cannot say one can be jealous without having some sort of insecurity about whatever the subject of jealousy is.
People who get jealous easily are mostly insecure. And are easilyscared that something or someone Will take something away from them.If you're territorial you're not insecure, but strong and you want to defend what you have or get more. But you won't flip for small thing's...That's what i think.
