I got ghosted after a couple of months of dating this guy and I want to confront him after work one day to find out why. What do you think?

We really don't like mysteries, which is why we'll stick it out to the end of a show we don't even like -- just to find out what happens. And getting ghosted is personal so in the absence of facts, we come up with all sorts of reasons for it and drive ourselves (& our friends) a little nuts in the process. Confrontations don't usually inspire open dialogue so I suggested a couple of other options she might consider.
