How to bring this up? Involves my mom dating again?

My parents got divorced when I was in 7th grade, & I'm now in 11th. My mom hasnt shown any interest to me in starting to date again, but I think she either thinks I wouldnt want that or that she is too old to be "looking." She is in her late forties (47 or 48?), so she still has 20-30 years left, & I want her to be happy. I want to tell her that I would be perfectly ok if she wanted to start dating again, & even if she wanted to remarry, but I'm not sure how to. Awkward much? Points for best answer.
