well that all depends how long the boyfriend and girlfriend have been together, at the least i would say he should no her name lol. if however the couple have been together for a month or two maybe he should no her birthday, and maybe after a year he should no her mother and fathers names, and her sisters and brothers names. it all depends on the period of time he has been with her or known her. hope this helps :)
If you don't know if your girlfriend likes you then you need to get to know each other better because she should like you before you become girlfriend and boyfriend.....
Ideally, you would be the boyfriend of your girlfriend. If you didn't know whether you were going out, you could always ask them.
Tell your boyfriend how you feel about it.
It could be. A mutual friend is someone you and another person both know. If you and a friend both know your boyfriend/girlfriend, then your boyfriend/girlfriend would be the mutual friend.
well ask her or she will tell you
If you didn't know he had a girlfriend tell him off. Why would he want to fool around with you if he already has a girlfriend. Also you might want to tell the girlfriend , she has a right to know what her boyfriend has been doing.
The only way you will know if and where your boyfriend is cheating is either ask him straight out (he may lie about it) or, take a girlfriend with you on an evening he should be with you and follow him.
definitely
Well, they're not boyfriend and girlfriend. So, they just know each other.
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.
yes you should ask her out. and being a girlfriend is like a step forward in your relationship with someone. i know some people who wait months to become girlfriend/boyfriend.
I think that the girlfriend should definitely introduce her boyfriend to her family first.
