What does it mean when a guy calls you his best friend?

SoulGirl
Been seeing this guy every week for 4 months, but we've only been hooking up and we are obviously getting to know eachother along the way. Anyways if when we talk (whenever we see eachother we have a good conversation) I'm talking about my friends he says "I thought I was your best friend". I asked him back if that means I'm his best friend too, and he says yes, "we're best friends"

What does he mean by that?
