This one particularly struck me, as I have felt a lot like you. I chose to marry my JW ex, and well, we've had one heck of a struggle, as she still believes in it and sold me up the river to be DF'd, but...if I had it to do over, I'd have taken my time. I also had another awful woman trying to manipulate me. I didn't handle either situation well, certainly not in the way that would have been healthiest for me.
Take it from someone who's been there: DO NOT GO BACK TO EITHER ONE OF THESE PEOPLE UNDER ANY CIRCUMSTANCES. YOU WILL REGRET YOUR DECISION. Please. Take it from someone who knows.
Loneliness is something I've struggled with, too. Perhaps it motivated my throwing myself into abusive relationships--and I'm the male, here, but obviously not a very strong or self-assured one. So I get it. That may factor in, if I may be so bold; I hope I don't offend you in saying that. But you clearly need some time facing the mirror and fighting your inner demons, working on yourself and coping with your pains. You can find good friends who will help you in that process. But don't look for a lover to do that for you. It's just not the time for it. It is tempting, but please, please don't let your emotions leave you open to getting used or abused.
Feel free to send me a private message--I'll be glad to talk further and be your friend as well, if you want. Wish you the best.
