Merry Christmas all!

How do you deal with or figure out if there is an emotional affair happening or even just leaving the door open for other guys?

I have this nagging suspicion based on comments and actions that maybe there is something going on. When we are out together and we run into old flames or guys she knows she gets really weird. When she talks to guys she gives off this vibe that she may be open to more communication later. I don’t know if that makes sense, it’s just a weird “the door may still be open” vibe. I don’t suspect any physical cheating though.

She would never admit to anything if it were true or would just brush it off. There have been some big financial lies/infidelity in our marriage that have put a crack in my trust. There have also been some messages to guys that she has told me about that make me wonder what else there may be.

I feel like the evidence would all be low grade fever type stuff. Like keeping conversations with guys going longer than they should and letting them flirt so she can keep plausible deniability.

Am I overthinking this?
