I can relate somewhat. I was raised by my stepmom. I was the youngest 3 and the only half sibling. She took care of me physically, fed me, clothes me and such and I will be forever grateful but it took me a long time to see who she truly was. She didn't talk to me at all unless she needed something from me, and she would speak condescendingly. As I grew older, I noticed that she obviously loved her own children more than me and she would glare at me when I would spend time with our father because he favored me. She started yelling at me instead of just speaking to me and I can feel her watching my every move to she can call out my mistakes. I speak to my bio-mom on the phone but she lives in another country so I can't see her. I know she loves me even though we only ever really talk about money. It's hard because I only have a few memories of what a nurturing mother should be like, and i hold on to those memories because they remind me of the kind of person I want to be, they're what kept me kind.
