MysteryMan don't worry, I too roll my eyes at times on here! Don't put up with it, not here, nor anywhere. The whole discussion regarding your weekend is a joke and I too am 
that your weekends has been pulled apart. If any one of us women spent the weekend at a guy's place, regardless of how healthy or unhealthy it was, there would be woops of 'go girl' and encouragement. As dolly has said in fact. I agree.
King your friend is verging on psycho. Tell her to let you know in advance of plans to come into the city, or understand that you won't be able to see her just because she is there.
As it goes, the sulking is enough for you to tell her to sling it. I would end this right now, for this alone.
Can i just remind - again - of the following:
If we are second guessing, in tears over people we don't know or have exchanged a couple of messages with, clinging to those who were NEVER right for us, or agonising about general minutia then dating is NOT what we should be doing. Until we recognise that we are lovely people in our own right, then how can we possibly think that anyone else would?
This thread is becoming a place where low self worth and poor self esteem is encouraged/the norm and it's less and less supportive of healthy and happy relationship building.
Until things are done differently, things will remain the same.
