Why do i cry when my boyfriend is not around?

i always seem 2 cry when my boyfriend is not around even if he goes 2 work n i go 2 work, i ave been wid him 2 months but i know he is definately da 1. i am 35 wid 3 children. i cant seem 2 cope when he is not around n sometimes even feel suicidal (how stupid is dat). i think about him all da time
