I had to smile at your title....

"I'm seeing someone, it's awesome, but I worry a lot"

That pretty much is what it's like for everyone, no? Not to make light of how you feel, of course.

Just a dinner with the parents? No....too soon.
A get together with a bunch of extended family like at a wedding or barbeque? Absolutely.

Is it a good idea to read this book? Do you think you might be trying to quiet your heart and let your head take control? (Sorry, I'm a strict romantic....)
