It is difficult to feel like you've lost your best friend.
But, if your W has done all this to you is she really being your friend right now?
I understand the desire to keep the road back paved and downhill, and I respect that, but I think it shouldn't come at the expense of your self-respect. So, keep it smooth, but only in ways that you will be proud of down the road.
I know that, for me, I find that I struggle with being assertive w/o feeling like I'm being a jerk or being punitive, but if you don't respect yourself and act as if you expect it from others, I don't know how happy you are going to be whether or not your W returns.
The other half of this formula is to be respectful of your W and her needs but recognize that right now, your relationship isn't the same as being married and living together.
