I've not posted yet, but have followed your situation. I know you're hurting and my heart goes out to you. I understand you reached your tipping point and you do not wish to work on your marriage. I understand your desire to divorce. I have given myself a fairly short window of time to see if my marriage can be turned around (no children involved, thankfully).
The only reason I'm replying to your thread: I think you need to slow down with the new relationship. You need to heal yourself before you can invest in love. Just be careful. Put this new "thing" on ice for a few months. Be alone. You've changed and you need time to get to know the new you. It's not fair to you or your new interest to jump in so quickly.
Take care, girlfromimpanema
