OK, I'm a girl; if she is mad at you then your in trouble! If she has randomly stopped talking to you she probably doesn't want to go out with you or she is hiding something (probably cheating on you). Or she may be mad at you because you did something wrong and you didn't realize you did it. Or another girl was hitting on you or YOU WERE HITTING ON ANOTHER GIRL. The best thing to do is talk to her; tell her to let you know when she is ready to discuss her feelings. When she's ready, listen to what she has to say, don't be defensive if you want her to be honest with you. The only way to resolve problems is talking about them.
girlfriend
girl; girlfriend
His girlfriend got jealous.
Dump. Get a girlfriend who will always talk to you.
When a boy keeps telling you about his girlfriend it probably means he really likes his girlfriend and likes to talk about her, but the only way to know for sure is to ask him.
If your girlfriend cries about when you don't answer her call, she probably doesn't like that you ignored her and wants you to fix that and talk to her more. When she calls, she misses you and wants to talk to you, so just do it.
If by sharing her you mean letting her talk to other people besides you and have friends then yes.
I'm guessing you mean a friend with benefits and if you are then talk to her about it and see how she feels.
I don't know about supposed to be as much as you might mean it can be. If it's a new girlfriend or if there was a recent situation that makes things awkward, then it can be awkward.
it means he wants to talk to you
It doesn't mean they like you maybe they are bored and just wants to talk to you
MArriage?
