Rob, I felt what you feel, last year. I had some long posts about it, saying how then I understood how my stxH felt when I tried to appeal to his AGAPI, logic, etc etc...
It is so much easier to start fresh with someone new. But I have the feeling the reward of choosing to stick to the "old" and bringing back all those loving feelings, cant compare with anything... K
Your last post sounds like me thinking in better English...
