I would second what many are saying - certainly red flags! If it bothers you enough that you have reached out, validate your feelings on this. Hugs or touching in and of itself is not unethical...but you seem to be expressing a pattern that is increasing in intensity. The message is way pushing, if not blatantly crossing, boundaries. It is important to have a healthy therapist with good boundaries. I am afraid for you that he will continue to push and then seriously violate boundaries. That is not a place you want to find yourself in. I speak from experience.

You can find better!! In my humble opinion, I'd say it's not worth the conversation with him. Draw your own boundaries, leave him, find another, and celebrate you honoring your own instincts!

No matter what you decide, keep getting feedback!
