Hanging out and flirting are different, but there is a very fine line between the two. When your friend is in a relationship, you need to respect that.
your friends boyfriend will breakup with your friend, and your friend will get mad at you.
even if you don't want either of them mad, your going to end up making one of them mad. so either tell your boyfriend that you like your friend, or tell your friend that you have a boyfriend.
if u have a boyfriend and he says that he most likely had sex with ure friend i dont wanna make u mad but it most likely the truth and a smart answer
talk to her :D
Of course he is going to be mad
Your friend is mad because you completely ditched her/him for your boyfriend. You were talking to them then your boyfriend came and you completely ignored your friend. You will have to be more considerate in future; it is not polite to just make out with your boyfriend in the middle of a conversation. You should think about this before you talk to your friend and try to see through their eyes.
You didn't say whether your friend was male or female. Either way, a friend is a friend and if you have a mature boyfriend then they would understand. Never give up your close friends over one boyfriend simply because he may get mad. Introduce this friend to your boyfriend and try to give some time to your friend, but the majority of your time to your boyfriend. If your boyfriend does not like it then it's a sign of immaturity and jealousy.
just ignore them or tell them the truth
If your friend did that, they're not truly your friend. Of course you can be mad. But keep in mind that your relationship must not have been string enough to break that easily. It's not all your friend's fault, nor your boyfriend's. Maybe you and your boyfriend should have spent more time making your relationship stronger.
he gets mad when u go out starts asking questions
depends , if your friend said yes to go out with your exboyfriend then i think so. But if she asked you if it was ok, and you said it was okay then you shouldn't be mad.
i think that if your friend is really mad at you because of something like that then she/he needs to get a grip and know that you cant hang just around them the whole time at school. just try to talk to them. if they dont understand then just give them some time. if you confrunt them and they say that nothings wrong then dont worry yourself about it. thell come around eventually.
