I switched T's, I guess around a year ago now. I had some pretty torturous attachment and transference issues with T1, which at the crossing point, I wasn't willing to deal with any more.

I interviewed a few T's over the phone, and met the one I liked best in person for a consult. All went well, and I decided to see two until I felt I could make a safe break from T1. I did not tell T1 anything about T2, though T2 knew about T1. The two-T at a time thing went on about a month, maybe more. I definitely felt like I was cheating, but felt that it would harm the therapeutic relationship more by disclosing If I decided to stay. Plus, disclosing was totally outside my comfort zone at the time.

I'll be honest - the transition was a really low point in my life, but I don't regret it. Make no mistake, therapy is hard and transference issues are still a problem for me, but certain personality combinations just work better than others. T1 was too good of a fit, if that makes any sense. The first few months with T2 were primarily focused on issues with T1, and dealing with the loss of that relationship. It was really hard leaving T1, as if someone died. But having T2 in place was a good safety net.

Keep in mind, the relationship with your T is professional - which means you are completely within your right to look around without 'telling'. We as clients are disadvantaged in therapy in all ways except this. We have the power to leave when we want, and give as much or little reason as we feel comfortable with.
