Single Parenting Support Group
Today being raised by a single parent is not uncommon. About three in ten children live in a single parent home. The most common type of single parent home is one with only a mother. However, single father homes are the fastest growing type of family situation; 60% growth in the last ten years alone.

50/50 custody is possible...but giving his history, not likely.
The thing about threats is this...they tell you exactly what someone has thought about and decided NOT to do.
Because he could have just done it already.
(Remember this when you get older and you start threatening your kids for what you'll do if they don't do something...)
As far as custody goes, try to keep records of when he takes the boy, when he brings him back, if he's on time, early, late, etc.
And like I said, most that will take you to court just do it...they don't mess around with threats.
Enjoy and love on that little one of yours,
