Thanks for your clarification re: the 3 stages of relationships as they apply to new relationships. Very interesting!...... and easy to remember since all of us here have those stages etched into our collective consciousness.
Regarding your current situation with GF I think that her responses to you really depend on numerous factors, including who (GF or her H/BF) initiated the break-up of her last serious relationship, the reason for the break-up, how long ago this happened, if the scar from that past relationship is re-opened frequently by joint custody issues, the type of relationship she had with her father (this may influence what she is looking for in a relationship), and whether or not she is open to 'owning' her role in the end of her last significant relationship, among others.
I'm sorry if I'm asking you to review info that is already here somewhere. If so, please just tell me where to find the pertinent information and I will look there.
On the positive side, you could view this as an exercise in tantric s*x.
