Based on a discussion w/ a friend..
If your AP professes deep love for you, yet what you feel isn't as intense.. but there is something there.. but it's not something you could be as sure about as your AP is about their feelings..
What would you say or do?
Pretend you are both at the same place?
Make sure AP understands you are a bit less intense about the whole emotion thing?
Change the subject?
Kiss AP so that he'll stop talking about all the mushy stuff?
I think in my case, I'd make sure she knows where I am as well as that I understand where she is.. and that she and her feelings would be safe with me even if I may not be able to reciprocate at the same level..
Or I may just kiss her to stop talking too :)
