Text her and ask her to have the courtesy to not leave you hanging; if she has decided that she no longer wants you as a friend, just ask her to please tell you so. If you get no reply, move on.
Well my thoughts on the matter is that friendship is forever. And as far as I can tell you would like nothing more than to go with option: A) and I agree with that 100% and if she is a true friend as well, and assuming that everything is alright within her life and she is able to get your messages. I would do everything in my power to save the friendship. Friends are very hard to come by, now more than ever. And I know just how you feel, I'm not very good at making friends in person either. So when I do make a friend in person I make them to last. But the feeling has to go two ways and from what I can tell she stayed your friend for 3+ years and I'm sure she still is. And if not then I am very sorry to hear that. But once again I would say option: A) all the way! Good luck!
Yes I agree with you there. It may very well be her friend's doing. I hate to say this but women seem to stick together most of the time. More so when there is a male in the mix of things. Most of us are very threatened by male's in friendships. Due to the simple fact that they get in the way. I don't feel that way but I know many women that do, and more often than not there is another woman to push her right down that road. But I like to keep a happy thought on it, so I would just keep trying and sooner or later you will find out one way or the other.
oh dear, well then just give her some space...let her go and be okay with it...if she comes back around so be it. Perhaps she has something going on..
In my experience, friendship between men and women is a tightrope few can walk. It eventually it requires 4 extraordinarily understanding and trusting individuals - you, her, and each of your partners. Not a good bet. I'd suggest making a variety of new friends including men. Putting all your eggs in one basket tends to drive people off the deep end.
