Jason became famous for being the pretty boy who stole Julia Roberts away from Keifer Sutherland.
He then dated model/actress Jennifer Jason Leigh for a few years and then super model Christy Turlington to rap up the 90's. As he hit his 30's the super models stopped calling. He spent the next decade in an on-again, off again relationship with Danielle Schrieber. In 2009 with her biological alarm clock buzzing loudly, and it becoming obvious she and Jason would never get married, she asked him to provide the sperm for her to be artifically inseminated. He agreed as long as he would have nothing to do, especially financially, with the child. They signed the papers he spent a few minutes in a bathroom and 9 months later she had a boy. But in 2011 Jason started hooking up with her again. That lead to him getting to know the son.
And when they broke up again, like they always do in May 2012 Jason decided he wanted the boy! He filed for 50/50 custody. This is like Jason giving her some milk and flour and coming back later to say that's my cake you made. Being a dad isn't about giving sperm, anymore than baking a cake is about giving some of the ingredients. You did the fun part and she did all the work. If you want to be in the boys life, marry the woman you strung along for 12 years now you selfish SOB. By the way you're hot clock has expired so your options should start drying up soon.
