It has happened to most of us.....I know it's hard not to take personally given the very nature of the "work". I agree with @sixpact....to him this is "just business" and sometimes it's hard to remember that especially if we have a connection with the therapist. My experience is that the best way to get over it is to jump back on a different horse. Something similar happened to me just a few weeks ago and it stung for a few days, but you do move on and get over it. There could be lots of contributing factors that went into his decision.....new relationship, wanting to make a change in his life, he was getting too attached or thought you were, another job, etc......the fact is most times we will never know.
