Don't I really don't think that the problem here is the thread per se... I know from when I was going through my separation and divorce just how much strength I drew from my MN thread. Perhaps you need to focus on your other thread that's all about you.
Maybe what you need to do is stop all dating and focus on getting your life a bit more straight. I think there's a lot of unfinished business with the ex that really needs to be tackled. Another man in your life won't make all of that crap stuff go away, even it makes you feel better for five minutes.
Not wishing to sound sour but I hope that the reason you're coming off the thread isn't because G has been in touch and made it a condition of communication. If I recall you left the thread at his behest previously. Anyone who asks that of you is wicked and petty and does not love you (I hope that's my over-active imagination dreaming up that scenario).
I'm sorry if my words offend you and cause you distress right now but maybe they'll give you food for thought at some point.
Good luck with finding some peace of mind. I know what it's like to not have it.
