I feel like I'm an old curmudgeon, but I don't see much point in being vague or doing some Jedi mind-bending DB stuff. If there's something you need to tell her, then tell her and use the most convenient least expensive method to do that.
I don't have any issue with saying something nice, I actually think that's a good thing. But, is it going to get her to come back to you? Hell no! It's just some nice comments; don't waste your time figuring out how to communicate. Just do it or don't do it, but don't expect anything for the effort. I really think it's that simple.
