I'm so sorry you are going through this Chummy!

This is just my own experience, but I believe that a very important part of therapy is acknowledging your needs and then asking for those needs. Bringing up your concerns to your therapist could be a great opportunity to push yourself to do something really hard and potentially therapeutic.

Regarding your actual concerns, I think that with human relationships, there is a normal curiosity to know the other person, connect emotionally and physically, and have relational constancy. Therapy can be very withholding, and unfortunately that can be a very painful part of the process. In my own therapy, some very childlike emotions emerged at different points. It was really confusing and embarrassing, but talking about it helped. TBO I'm still processing a lot of the emotions around triggering situations.

Hope you end up doing what feels right for you!
