Ugh, this gives me flashbacks to my ex-stepfather, who ADOPTED my little brother and then wrote him out of the will to make his other kids happy. He also kicked him out of the house at 16/17 for not doing his chores while recovering from knee surgery, ignored him completely once the divorce started, and then made out like he Really Did Care and my mom was just getting between them. Fortunately my little bro is not stupid and ignored him.

My dad, actually, is a better father figure than my stepdad ever was (my brother is not related to him). I refer to him as my bro's reverse step-dad. Little bro even lived with him and worked for him a while this summer before college.
