Does this sound right ? this quote You shouldnt open the door if you arent willing to walk in?

i haven't heard from my ex in almost a year. Well he got in contact with me tru myspace we met up and we saw each other it was magic we couldn't stop holding each other and kissing it was amazing . I know he still loves me but I been sending him texts emails and ive gotten nothing in return I don't know if he wants to take things slow if he has someone i dunno...he said hes single and hes been alone since me but im confused why would he contact me almost a year later make it obvious that he missed me yet let a week go by and nothing... Whats going on and does that quote make sense for this situation Thanxs so much...
