This is driving me mental!

Ok so this girl who made me the cd right, i like her, not sure if she likes me but weve been hanging out and like all the same stuff and shes nice and we get on well etc. etc.

She did have a boyfriend ages ago when met her, not sure if she still does but she never mentions him to me or anything so perhaps not.

I was at her house today and we watched alan partridge for a bit, but then she had to go to work. She invited me back over to watch it another day, i joked saying she is only inviting me because she wants to watch my alan partridge dvd, she agreed as a joke but then said 'im only joking, its good to spend time with you! and the dvd is a bonus'

should i go for it?

i just dont wanna make it all weird if she doesnt like me as shes cool, and i dont wanna be crushed!
