if there are true friends then they won't make fun of you but help you out of it asap. If you tell them tho you have to be willing to breakup with her because I'm pretty sure they won't approve of you being in a relationship like that and that can put a strain in your friendships.
if talking 'bout your boyfriend he probably hugs you in front of his friends so they can think that he has a girl and he is cool and when you are around your friends he probably is ashamed of having you as his girlfriend
well talk to her about this and if she doesn't have a good enough reason simple solution break up with her, she shouldn't be ashamed to admit she is going out with you; even with her friends
first you need to ask yourself if your ashamed of your boyfriend or if your friends are and more importantly if you like this guy you shouldn't be ashamed of him. you should like him for who he is not what he looks like or what your friends say about him. and if your really that ashamed of him then you might consider whether you wanna date him or not.
show her she's special and that no matter what, you will be there for her. just take her out somewhere, even if its just to a park or out with your friends, show her you're not ashamed of her and make her feel beautiful.
that means he is ashamed of u in public around his friends
have a threesome
if there your real friends then they would be supportive of your relationship, and you shouldn't let your friends make fun of you girlfriend. remind them who has the girlfriend around here, And maybe they should get a girlfriend. But if you tell them to stop and they won't then forget them.
that is ultimately up to you. if you love her, wait. however, this is only if you think that you will comfortable knowing that she was torn at one point and realizing that you and your friend may no longer be friends afterwards.
If your friends laugh at you and your girlfriend then don't pay any attention to them, and stick up for your girlfriend. That will make your relationship go farther. And you can also know that if they make fun of you, then there not true friends.
