I can't get over this crush. I'm still obsessed with the guy my wife caught me flirting with
Oh no, really? Would she understand why you flirted with him?
It depends on how I tell her. If I tell her the truth she might understand.
Telling the truth is always the smartest choice. Do you think she'll want a divorce if you tell her what's going on?
I don't think she'll want a divorce over flirting.
Good, then be honest about the attraction you're feeling. Make sure she understands you are still attracted too and love her, but that this is just a crush that will never be acted on.
