I am sorry to hear about your biological father. And I am glad that your step-dad acted more like the genuine article.
This is really big for me. I don't have to hide anymore. I am separating from my wife, and staying with my family, while not ideal, is something that I really need. Now that I don't have to hide from them, it won't feel like hell living with them. Well, not a special hell, just a normal, living-with-family hell. It also means I can afford to take care of transition, catch up on bills, and most importantly, take care of my daughter while doing the other two. It also means I can afford to jump back into school full time come fall.
I can simply start going out and find myself, be myself, and be the best parent for my child. My dad may never know what a huge kindness he paid me. Funny how such a small, silly thing as acceptance can free others around you.
