When should you tell a new love interest that you are still legally married and waiting for your divorce to be final?

I was in your situation before I met my present husband. Because divorce can get messy, I told my new boyfriend after the 3rd date. It was painful for me to talk about and I wanted to be sure he was worth me pouring out this private part of my life. I just warned him what he could be in for. Thanks heavens he didn't mind. I feel you should tell your new love interest soon. Honesty is always the best policy. Good luck Marcy
