Hello, I have been reading WS for ages, finally made an acct. I have been following this disappearance since someone posted about him on the McStay FB page.
I am beginning to think he left with another man. Maybe his wife finds out he was having an affair, he says he will end it, she finds out later he has still been texting with this man. They (or she) plan the trip to Italy to get away. He is tired of living a lie, they argue. He leaves. I don't know why he doesn't take his wallet, but he leaves everything for his family. Maybe he feels guilty for being gay, for trying for years to be someone he is not. He cannot even bring himself to contact his mother. He meets with his bf after work, they drive to the house so RM can do something. The bf drives, moving the seat forward, they go to train station where the bf's car is stashed. Maybe a wild theory but it happens, and IMO explains all the secrecy.
