If it were me, I would try to refrain from too much wild speculation, so the situation doesn't become bigger than it really is. This has a fairly simple solution: ask, ask, ask. The test for your T is this: can she provide an explanation for her behavior that 1) makes sense to you, and 2) leaves you feeling good inside, without any weird or uncomfortable overtones. If she can't, then you need to pursue it, and even push for more clarity. Don't stop until you feel like you have your answer.
Mona, in the end, if she is doing something that you don't feel right about, she needs to try something different, or you need to find another T. You sound like your trust in her is tenuous, and that's not an effective foundation for good therapy. You deserve to be in a therapeutic relationship that inspires you, makes you feel safe, and challenges you to grow. Go get it!
