The boundary I am interested in setting is one with her saying "I love you" and then kissing me, etc. As much as I'd like to ask her about it, I think it would be more productive for me to just set this boundary personally, so that if she does tell me that, I just say thanks, and if she asks if I want a kiss, or she tries to kiss me, I would just say, not now, thanks.
The boundary is fine, but just put it in force, you don't need to tell her about it.
