Leave Him!
Not unless you are paranoid or insanely jealous.
Your boyfriend should be the guide to show you how to "deal" with it. You should be polite and courteous. If there are jealous feelings or you feel you cannot deal with it , you know it is time to move on.
If they are out to get you. They hate you.
She is your boyfriend's sister and you are immature and have no self confidence. His sister is no threat to you and there is no need to be jealous of her. If she meddles in your business with her brother then you need to tell your boyfriend to speak up and deal with the matter at hand.
i think you should talk to him about it and stay with for a few more weeks ,and if he is still jealous break up with him because he cant deal with the fact that you have a good relationship with a nother person.but its not a boyfriend girlfriend relationship.
I would say no... but it depends how jealous he is? why is he jealous?
I don't see why your boyfriend would be jealous if he is with you.. Please be more specific on what the problem is.
no it's not true that your boyfriend will make you jealous. Because It won't happen.
tell him there's nothing to be jealous of.
well if your bestfriends ex boyfriend is jealous of your boyfriend then tell him to get a new girlfriend or make him even more jealous for your frend because I'm pretty sure she would like that
no.
make him jealous
