I like your spunk! Sounds like you are coping well, good for you!
Yes, a legal sep is less than a divorce, but it's a pathway to the big D. Makes it all easier if one spouse decides down the road to pursue D. My H is doing leg sep so I can stay on his insurance, (his idea, not mine, H said we could do the D if I "want"), as I recently lost my job in April. A leg sep splits all assets, just like a D, but still married.
I agree, enough is enough. If they want out of the M, so be it. It seems to be the only way for them to fully understand what they want. 60% of WAS's regret their decisions, did you know that? My DB coach told me that. Amazing...
H owns the house to I will be the one "getting out". The get out date is Dec 1.
