Ha! It probably is something simple like not wanting to ruin her holidays or they have a non-refundable trip booked.
But what about ruining his wife and kids' holidays, you know?
He does say they exchange "I love yous" and "a part of him does love her" so I know he's probably feeling some guilt over bringing her into this, hurting her, etc...
And I do get that.
But I also know with 1000000% certainty she KNEW he was married and she had to realize this was a real possibility. Obviously she does, that's why she's still so insecure about him talking to me, etc...
