At the risk of sounding harsh - you knew what you were getting into also. So the reality is - you would have been wise to be prepared for what may possibly happen. Equal responsibility.
Not that it helps with the hurt and distress of being released, but being aware is what it is all about.
Submission being a gift - maybe it is - but don't suffer him the guilt trip of it being your gift to him. It is a gift you have been given to share with whomever you chose. Just because he has decided not to share in what you have to offer doesn't make it less a gift.
So you pick yourself up and move on. Hurts like hell - and isn't a pleasent pain. But try not to look at it as a mistake, just another lesson to learn from and try not to repeat it in the same way.
Oh and my typing sucks this morning .
Peace and Rapture
