While your ex is filling in your time, you are Not meeting the one who is Right for you. Ask her WTH, and believe her answer & act on it, or cut her off!

I realize this post is several days old and I cannot speak for your ex but I can speak of me. I have been married twice & I have had 2 long term relationships. I am friends with all 4 of those guys. After my 1st divorce we tried to go back but there was too much mud in the water for both of us, especially for me. I believe there is a reason 2 people start a relationship in the 1st place and for yours to have lasted 20 years there is/was something strong there. Be sure to talk to her - not in the 'are we getting back together' type but in the 'I am enjoying our time together and I don't want to be misconstruing what I am feeling'. Also, as others have stated make sure you know what you are looking for.

Not a woman, but I have one observation and one suggestion. Seems as if y’all just downsized your marriage. RUN!
