Me and a good friend used to go out at least once a month (usually more) and have drinks. We were both single so used to not go out "on the pull" but we would chat to guys, have a laugh etc.
A different friend set me up with a good friend of her and after the first date I knew it was going to be special. The friend asked me if I'd like to go out the weekend after and I declined.
I am now officially in a relationship, since then I have heard absolutely nothing from my friend - she seems to have disappeared off the face of the earth. A mutual friend had everyone over for dinner last week and she didn't even come to that.
I feel like she is acting a little childish, or I am being unreasonable?
