no contact crush

guys important question: i liked this guy since 8th grade and it’s been a whiiiile since we last spoke.
i felt a connection between me and him, and i still think about what could have been between us two.
please. i don’t know how to break contact or if i should, so i figured that i might wishing him happy birthday on his birthday this year… but the big problem is… i don’t even know when his birthday is… please help a girl out.
i appreciate it
