I’m “separated”. It took years to get him to move out… but only weeks to start dating. I was SO done with my marriage.
Six years later, we are still “separated” but only because we can’t come to terms on the divorce (and the fact that he’s an ass… but I digress). We are each living with the people we plan to spend the rest of our lives with and the marriage couldn’t be any more over. It’s just a matter of making it legal.
So I guess my point is, that sometimes it’s more a matter of it taking a long time to iron out the details than not being sure.
On the other hand, I have also had men tell me that the are “practically separated” only to have an angry wife call me and ask me why my number was in her husband’s pocket. I always came clean and said “because he asked me for it, was cute, and never said he was married.”

Let him deal with bed he made.
