The answer is up to you. If you feel embarassed to be his girlfriend than maybe he isn't right for you. Only do what you think you should do.
You should just ignore them and date someone else better then her or him.
no, Because your the boyfriend and he is an ex only.
only if you want to be really harsh on him and his girlfriend
Friendship should be all about sharing moments of happiness together. If you make your boyfriend cry, then you may be a bad girlfriend for her.
No because she might have a boyfriend
A girlfriend can not get a military discharge for her boyfriend just because he wants out of the army. He should talk to his superiors and find out if there is anything he can do to get an early release from the Army.
If it okay for your girlfriend to work for her ex boyfriend as long as both of them have truly moved on, and as long as you feel okay about it. If you feel that them working together will cause issues, you should be honest and discuss your feelings with her.
Yes because she well love you
definitely
No, you should not email your ex girlfriend to try and get her back because she has another boyfriend. You had your chance to make the relationship work out with her and since you didn't then it time for both of you to go your separate ways.
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.....
I think that the girlfriend should definitely introduce her boyfriend to her family first.
