One other thing, even if there is a OW he is making a move back to you, that is good no matter what. Could you be hurt again? Absolutely. However no risk, no gain. If there is an OW maybe he is looking for a safe landing spot(you) before he dumps her. Like I said before you will know eventually, just continue to have patience.
This is similar to my thoughts, GAG. Good to hear Lance is on the same page. Whenever I think H may have been with OW I remember that he is not too confident about their relationship when he is calling/texting/visiting me. Likewise, if your H is involved with OW he is not too confident if he is sending you messages and signing messages in the intimate ways you have shared in the past.
My experience is that when OW is in the picture, no information about trips and outings is usually shared. It's all very secretive.
There are similarities and I appreciate your support. Thanks
Also, don't forget to re-read Dia's thread for an example of the re-connection phase.
