No man alive is worth all the pain your actions will bring about.
You have no idea who this man really is, everyone puts on a different face at work to a certain extent. You are projecting a fantasy of all the things you wish you had onto him and he is willingly going along with it. He knows exactly what he is doing here.
Is the fact that he is prepared to flirt/emotionally manipulate a co worker (ie, a captive audience) while his wife is suffering from depression not a great big honking red flag to you?
Read that back, does he sound like a nice person?
Have the courage to sort your own life out before you use him as an escape route from your marriage. You know, like an adult would. Stand on your own two feet if you’re so unhappy but don’t bounce from man to man like an insecure teenager.
Think about his wife and children - not just what he has told you but imagine for a minute they are good, kind, caring people not monsters that are ruining his life. That’s just him exaggerating to gain your sympathy. It’s worked, by the way.
Stop being so gullible and immature, real life is not like a Hallmark movie.
Obviously, you will ignore all the people on here echoing the same advice because the lure of an exciting, dangerous, passionate affair is just too good to miss.
You are a cliche and this will end badly, his lines seem quite polished - he’s done this before.
