I've regretted telling things to my therapists. I tend to be very open and honest, and not just with my therapists. Tell what you want, when you're ready.

I haven't forgiven some people who have hurt me. I still cry sometimes over the loss of my animals (dogs, hamsters and others). I don't spend every minute or every day hating or mourning, but I don't forget. I don't believe forgiveness is necessary, and it's not always good. That's just my opinion. And I will always remember my pets. I have wonderful memories, but also miss them very much, and sometimes cry. If others have a problem with that, so be it.

I've never had a therapist tell me I need to forgive anyone. If s/he did, I'd say I disagree. If I felt the therapist pushed me to forgive or wouldn't focus on things I considered more important, I'd find another therapist.
