Hello Jet, my opinion is this, I think its ok to send your son a message direct. He's 19 so he's old enough to make his own mind up about replying to you and what he wants out of a relationship with you. You could send his dad a message as a courtesy but I dont think its needed. I think its important to think what you want or need out of the situation and be prepared for not getting what you want. Put yourself in your sons position, he might find it quite hard at first but who know's. You might give him something to think about that he doesn't act on straight away but considers. All im all its a gamble but if you want to make contact you should do it. Good luck.
