hmmm. i think what also might help is if u get him to really love people outside of ur family like a good friend or something, make them bond, when ever ur friends around let her hold and play with him. then once when hes inside try leaving him with your friend and go outside till ur out of site...he should feel cofortable enough with her cuz he knows her well enough. try it with other people less prominent like a child , or a nother dog, until it gets to the point where hes left with something that doesnt have much interest in him, like a child, or just maybe someone he doesnt know to well. this will hopefully make him more independant, and slowly get used to not having you around
