Your post makes me incredibly uncomfortable. I literally felt my skin crawl.

I might be repeating myself from a previous comment, but I feel this needs to be reiterated.

Her behavior is beyond a boundary crossing. If you were to report what she is doing to a licensing board, there might be enough grounds for her to lose her license.

I know you love your therapist and she has been incredibly helpful to you. I don't want your attachment to her to be minimized. Leaving her will cause you tremendous pain.

This being said, she has extremely poor, unprofessional boundaries. It sounds like she is meeting her needs through you and has become enmeshed. It doesn't sound like she is putting YOUR needs first. This is what therapists must do.

Therapists are at a very high risk of ethical violations when they are going through a separation/divorce or other periods of interpersonal stress. I don't necessarily think she wants to sleep with you (unless she has said/done other things), but poor physical boundaries (touching others without their permission) also indicate she has extremely poor boundaries overall.

If I were in your place, I would not stick around to wait and see if her behavior might become sexual in nature. Furthermore, if it does, how would you react?

From previous experience (an older female mentor becoming uncomfortable enmeshed with me), I believe these boundary crossings will escalate. Anyway, we cannot predict the future, but I can tell that this is NOT headed to a healthy end.

Most importantly, I know that what a bunch of strangers tell you on a board will not dictate your decision. However, please listen to your gut. It's there for a reason. From what you are posting, it sounds like your gut is identifying lots of red flags. I understand that you don't want to believe it.

I hope you decide to find an ethical, professional therapist who will respect your boundaries and puts your needs first.

Best of luck.
