When there was si that I didn't particularly want to change or stop at the moment but figured t might want to know, I told her that it was there, and the only reason I was telling her was because she may want to know it was going on, but that I wasn't really in the mood to talk about it, and I wasn't ready to give it up at the moment. I also assured her I would tell her if it became concerning (hit a level of severity or frequency that might lead to more issues).
Though, this was only after t and I had already established that si was in my history, and that I knew she wasn't going to freak out on me about it...

Good luck today either way.
