The similarities in our sitchs is uncanny. I've often waited "for the other shoe to drop."
IMO...keep doing what you're doing. Don't worry about the R talk. I know it's hard (at least it is for me...I like to know where my M stands) but when it comes down to it, words are just words. Actions mean so much more. Enjoy your time with him and make the most of it. Have fun. Be the person he first fell in love with.
It's hard for me to not know where I stand as well. It makes it worse when I have friends asking me about it and pressuring me to resolve it one way or another. It makes me wish I'd never told them but at the time I needed the support and hadn't found these boards yet. This place is a godsend and has helped keep me sane over the past month or so.
