This, like a lot of other things in life, is unanswerable mostly. Because we all hav different standards and opinions, we all rate things differently. But to me, you have to be open and honet with each other and talk to each other. Lean on him/her if you need to, and don't be afradid to tell them how you feel :)
have a threesome
Well if he is your boyfriend then aren't you his girlfriend. And if he is crazy in love with you isn't that a GOOD thing?
Be her perfect boyfriend (or girlfriend as the case may be).
Boyfriend and girlfriend
Yes. A very good movie to your with your boyfriend/girlfriend. It is quite romantic.
a werewolf girlfriend or boyfriend
say bye bye
Well, I think that being a boyfriend, or girlfriend in this case, means that you need to talk to him. If you really like him then you would want to talk to him all the time. The point of being in a relationship is getting to know your girlfriend/boyfriend better. If you don't talk to him, how are you and your boyfriend going to build a stronger relationship? So to answer your question, No I don't think you are being a 'good' girlfriend if you never talk to him.
Never cheat on her, be a good boyfriend, do not get mad at her, ect.
Who's the better kisser.
