am i socially inept???

At times i wonder : How do you know when someone really likes you????
I always tend to meet people who hide.. so it's cool to be around you, but not to fully show what they feel.. cuz.. who knows what could happen?!?! :P but ! I know where i can be totally nerdy and knowledgeable and wise in some areas in others.. i am completely and utterly beyond common shades of doubt or sense NIAVE!!! really.. and i am sure no one believes this is possible.. but it happens.. so Duh! moments occur where i realize.. I like this person and we're cool together, but I wonder how much they really like me.. And maybe this is only b/c I know.. i do that. Send mixed signals.. b/c i don't know if it's safe to admit such things.. like.. I like you!

It's happened b4. . . when i met my last boyfriend.. he thought i was joking.. when months after we got together i told him.. When we first met and you were in my apartment and we were chilling all those signs.. . i tossed them away and knocked them off as silly.. i really didn't know what you were hinting at.. Dumb me! I wasn't looking for them.. I had already decided we'd be friends and just friends, so signs at something more.. i wasn't getting..

or maybe it all boils down to.. i don't think i deserve this so i reject it.. dumb..
for such a smart girl.. I sure have some socially inept moments..
