laugh.. and just say "chill out".. she sounds like one of the clingers. They usually begin to treat you different when you tell them, your not up for all that mushy stuff right away.. Just be prepared for that, and never let them know that you noticed a change in their behavior.

When she asked "what are we", I did unintentionally laugh, and just told her off the cuff that we are "undefined". she sarcastically said that what i said was "really deep". She did mention that she had several ex's who fooled around on her, and one guy, probably a PUA in fact, who basically hit and split pretty recently. so thats going to be rough to overcome :/
