Given how much you struggle in your relationship with your T at times (and believe me, I can relate to that), I would think long and hard about why you want to broach this topic. Not to say that you shouldn't do it, because no topic is off-limits in therapy, but there is a certain balancing act here since the potential for this topic to open up soul-crushing pain for you is quite high. I would ask myself why I want to know, what yes or no or evasion would mean to me, what love looks like or feels like to me, etc. I don't know that conversation is likely to have an outcome that will make you feel better and more secure, and I think it's worth recognizing that that could potentially make this a Pandora's box.
