The only thing that goes on Facebook that is related to our relationship is wedding planning-related stuff. I don't need to post about how happy we are because I am too busy being happy with my partner. Just as I don't advertise our fights because it is our business and we always overcome them.
This is what it was like dealing with the ex/bio-dad, and in return he and his family made little to no attempt to be a part of my child's life, plus his wife kept him from being a part of it even more when she came into the picture. The last time he contacted my child was December 2010, and since then there has been nothing from him. And yes, that does make him a deadbeat.
