4311, I had time to give to your sitch this weekend and I have very little time during the week to be active on this forum, although I do check from time to time. Sometimes I just observe as is more the case, these days.
Having said that, I agree with Tori. I think you have a lot to offer this board and other members and I encourage you to provide your perspective to other members of the board, even if they may not be open to hearing it. I'm not saying to push your perspective, just engaging others on this site may help others AND... it may allow you to practice being engaged with others, especially when there is no other intrinsic value to be gained except for that experience.
I want to leave you with one last thought this evening.
Consider how X1 felt when you moved on. Remember that you moved into an R with X2 so did not have that "down time" that many have between partners. That time that many LBS sit and think and wonder "what went wrong".
Imagine that she may have been waiting for you to make the move, thinking to herself... "if it was meant to be... if he really cared about me... he will contact me..."
and yet... you did not...
You may think that if it is meant to be with X2, then she will still be there when you finally attempt to re-connect with her...
