Because of a particular incident, I originally left our M bed, but also told W that I planned to earn my way back. Then, after almost 2 months of being the best H I could be, I announced one night that I was returning to "our" bed.
Wife said fine, then I'll take the quest bed. Not what I wanted of course, but I'm back in the M bed. That was over a year ago! We're still separate, but I hopeful for her return.
Another thing I like to do is continue to call it "our" bed/bedroom. Not mine or yours. I makes a difference, I think.
M: A really long time. Crisis: 5 years. She's still worth it.
Life is never made unbearable by circumstances, but only by lack of meaning and purpose. -Viktor Frankl
