Wow, LoosingControl21!! That's great!
I'm so, so glad that you sat down and chatted to them about it and I'm even more glad that they're being there for you, supporting you so much. That's great! They must love you very much.
Maybe your Step Father is being distant because he's shocked and upset by it and doesn't want to hurt you by showing that? Maybe he wants to let you and your Mum sort this out together?
I hope you get to see someone who will truly help you

You deserve it.
