When I was living with my BF (now ex) he never asked about therapy except once he asked if I ever talked about him in there. He seemed uncomfortable with the whole idea of therapy and thought I should just rely on him. He was a really loving boyfriend, so it's not like his not asking about therapy meant anything bad. He just didn't have experience with therapy himself, and he felt insulted that I thought someone else's advice was more valuable than his. In time I explained it enough that he wasn't insulted, but I don't think he even knew what questions to ask about it, anyway.
