She is a sweet woman and the last thing I want to do is blow up another R. Not that there is one, but, well, you know what I mean....lots of feelings on both sides starting to simmer.
Easy, tiger -- don't overthink this, and don't start thinking about this being an R and worrying about blowing it up. Just enjoy yourself, enjoy the company, and relax. Just my O, but I don't think you're over your W, and thus starting an R with this woman will not be in either of your best interests.
Again, don't try to dictate a faster or more serious pace than is likely healthy or good for you. Just ride the wave nice and steady. Just my 2 cents.
