you don't have to miss a period to be with child.

but inquiring minds would like to know.

Well if he's not doing what he should on his own, and i don't know if he stays with you or not, you can not change someone if they don't want to. But there's always a saying mama's baby daddy's maybe. not saying it's not he's but saying that the mother of the child always the main care taker a mother will not leave their child. TAKE HIM TO CHILD SUPPORT and hopfully he change when somebody else is telling him what he needs to do (if that helps). go to school, start working (if your not) and be the back bone your son needs.

I would make my child do research on what it is that their doing, make them write about the side effects and damage their occurring, and perhaps make them watch a film about it, change who they hang with, and always check their belongings, and ground them.
