This has really made me think, and in fact, even though a proper affair would devastate me, I actually think this is far worse.
If I put myself in my husband’s shoes, imagine the thought processes, and practicalities, the considerations before, during, and after sleeping with a prostitute, I cannot even begin to imagine how I would ever be able to look at him again, let alone sleep in the same bed.
What was the first thought he had?
Why did he think this was a good way to deal with his feelings/needs?
Did he make lots of efforts to reconnect with you first, and you left him out in the cold?? If so, did he then think, maybe I should talk this through with her? No.
Even having said all that, the fact that he confessed, and TOLD YOU HE DIDN’T ENJOY IT would be so beyond anything that showed compassion, or self-awareness. I almost think that’s the worst part.
Make a huge mistake, keep it to yourself, get tested frequently, while staying away from your wife, until you can guarantee your safe, and then move on. Leave, reconnect, whatever, but don’t tell her and expect it ever to be OK ever again.
