when a wayward spouse suggests separation so they can "figure themselves out" what they're really saying is I'm going to pursue a relationship with someone else. I'd like you to hang around as my plan B in case it doesn't work out. Ask yourself if you like being plan B? I promise you this. She won't respect a man who is ok being plan B and no one can love a person they don't respect.
That's exactly right and exactly what I did in my first marriage. I have so many regrets...way too late after the fact. But that's a different story. WW don't understand the full impact of destruction on others' lives for years. It's been 12 years and I'm just now really processing it. Anyway, it's true. You don't want to be plan B. Show her your boundaries and she will respect you.
