If it helps, I am separarated.
Only because divorce is taking a long time. It was filed almost a year ago.
Ex lives in a different country and he is only in contact with DS, or because of DS.
Tbh, I have stayed away from separate men mostly because there's enough drama in my life already.
But if I was single and 100% free I might consider it in special cirumstances. That would mean feeling 100% confident in the relationship (no second guessing, meeting friends and family, having almost total dedication) and that he had divorce proceedings well under way.
Good luck with it.
We have all given too much time to wasters at some point or another.
