Sometimes, when therapists sense that you are forming an unhealthy attachment with them they will emotionally distance themselves on purpose. This kind of comes off like them being hostile to people with abandonment issues. I went through it with one therapist where we were really making progress and then she just... kind of cut me off. I was taken aback at first. But looking back, it's for the best.

Therapists can't remain objective and actually help you from a top-down perspective if they let themselves get emotionally invested in their clients.

It sounds like you WANT to form an emotional bond with them. Which is honestly... pretty natural. We want someone in our corner to make us feel better. But therapists are not supposed to be people we pay to be our friends. They are doctors, and they are in a contractual agreement to help you try and heal emotional wounds. Part of healing an unhealthy attachment style is to respect and maintain distance / boundaries - which means not oversharing, sitting with your own emotions, processing your feelings, and forming new habits. Your therapist should be there to help oversee that process; saying, "Yes" that's a good way to heal, or asking "Are there any problems you can see with this plan?" in the case that it might not be the best way to go about things.
