How long did it take you to get over your first love?

Lindsey
There is someone I have been involved with and it is not going to work out (custody of him not committing). I am very upset because he is the first person I've ever been involved with- first kiss, first sexual experience, first "relationship". 
I'm feeling very sad because I was really into him.
