I think that if you starting to think about termination, that this is the time to tell t what is in your heart while you still have the chance. Just be prepared if your t says she can't be your friend. There are certain ethical considerations that she must take into consideration -- and although it may not feel like it, the restriction is for the client's good. It's hard to transition from a relationship that has been between the "carer" and the "cared about." There is an inherent power difference in the t relationship. It is designed to be that way. But transitioning to a friendship changes the whole dynamics of the relationship. Some people are able to make that transition, but many are not.

Keep in mind, too, that if you t says you can't be friends, she may still make allowances for rare, brief contact via email, letter, or phone as a way to keep your connection and let her know how you are doing. Every t is different.
