Jp, from what I have read, I think you need to take a long, hard look as to the reason(s) why you felt you withdrew over the weekend. Is it too much pressure? Are the expectations too great? Are you worried, or trying to protect yourself from getting hurt?
Hopefully you are able to open yourself up again in order to communicate with your W. Perhaps you could even tell her something like, "sorry I was a little off on the weekend, but I feel better now, lets go do something fun".
