2 years isn't a law but what is strongly encouraged by their licensing board. Different boards have different rules. For LCWS it is 2 years. For LCPC, they should never form a friendship. I believe the 2 years is so the client is in a different place and less likely to be really hurt by the friendship. If a client becomes friends with their T and something goes wrong the Ts license could be on the line. Plus many Ts do agree with the rule in order to protect the client. If the really car they want to the best possible by the client. I know it sucks 2 years seem like a long time. If in 2 years either party forgets our decides the no longer cares then wasn't the relationship built on the therapeutic relationship rather than mutual friendship.
