sorry that i'm late on this lies, just wanted to add my 2 cent, they kind of gave me my ss son, when he was 3 yrs old, my ah and i seperated for a good 3 yrs at one time while he was out drugging, and his son chose to stay home with me and my kids and i choose to keep him. it was hard financially, i didn't have any support from either parent but my intentions were to give my ss a stable home. even though, i keep my ss, i still at that time chose to stick to my boundaries concerning dad, maybe you can too. jmho
i think that the choice is yours but sounds like you all are a family, maybe for now , you could just keep the child if possible, i think that maybe in the long run, it could turn out to be a better deal for the child.
