This thread...eek. Sooo...
Last year, I took my kids and left my husband. We were separated for about 5 months, and I fully intended to divorce him. During that time (and honestly a bit before the physical separation occurred), I found myself in a relationship. Ok, it was less that I found myself there and more that I was so sure my marriage was over and I wanted to be with someone new who could say all the right things to make me feel like maybe I wasn't as worthless, ugly, unloveable as I thought.
Anyway! Back to my point here-
God had other plans for me and my family. Even my stupid, stupid choice to be with this other guy didn't get in the way of God salvaging my marriage. And I'm beyond grateful that He did and my marriage is better now than it ever was before, even with the healing both of us are going through.
So my advice to you is...
Stay away from separated (MARRIED) women. Even aside from the possibility of them reconciling with their husband, it's a bad idea for so many reasons. Speaking from my own experience having Been separated and facing being a single mother, gosh I was a wreck. My emotions were all over the place. I was completely unstable a lot of the time, just from the stress and sadness and...everything. I honestly became an entirely different person, and my decisions were...iffy, at best, during that time. So, if you go after a woman in a similar state, no matter what she says to the contrary, she's super vulnerable and it would be taking advantage of her (not that she isn't still responsible for her choices, of course she is).
Again, this is my own experience, but I just can't stress enough that you should stay away from a woman who is separated.
