Big Dog, I understand your dilemma, but I think we are getting into double standard here. It is OK for you to see other SP but not OK for her to see clients?
And you are probably more in the wrong cause you are doing it behind her back and paying for it, whereas she told you about it and she makes money out of it (ok the money part is shallow)
How about a novel idea you tell her also
This brings an interesting question which I will probably start in a new thread:
Why do we start seeing SP? Would you want to see SP if you were in love and harmony with the one you are with?
So keep dating her for now, the answer might come later as the relationship develops.
(actually this new thread I was talking about would be too personal for me, forget it. Better to have loved and lost than to have never loved before)
