Transference, counter-transference

What to do???
I had a tremendous amount of transference during my years with a particular therapist. I haven't seen him in almost 6 years, but I need to deal with more issues again. I know he had some "counter-transference" going on. It was obvious by things said and unsaid. Both of us seemed to be constrained by the therapist-patient relationship. Had we met under different circumstances, it's possible we would have had a good relationship. Now I'm a bit nervous about going back to him. I've more or less "gotten over" him and I really don't want to start having those feelings again. The problem is, he is an excellent therapist! The friend who referred me to him thought so too. He got me to change my entire way of thinking. I don't know how this happened. I even told him at the beginning of one session that my thinking was changing. He just smiled. My self-esteem was in the sewer when I started with him and now I don't even know where that sewer is.
