She says she wants to "take things slowly", any thoughts?

I think with time it comes. I guess its really your choice to wait and see if she's stringing you along, and not taking the relationship seriously. Every relationship i've been in, I never jumped into , but the ones where they told me to take it slow, normally just used me as a comfort zone, since most people feel very safe around me. When I hear that, it really pushes me away. I mean I never rush the relationship, I let it flow, so whatever happens, happens. So I know I'm never rushing anything or going to fast. You always have to be on the same level as your partner, and knowing/understanding them personal and understanding their body language will get you very far.
