88...I do think webgoji has grasped the situation, and given you some great advice, too.

I would definitely approach your Dad about having some alone time with him, to talk about your concerns and how all of it is making you feel. And be sure and ask him for some alone time on a regular basis----so that your relationship and communication always have an avenue that's safe and protected.

You might also want to discuss things with your Mom. She will always be your Mom, no matter what---and should still be nurturing and supportive of you, even if you live apart.

Both parents have the primary job of making sure you are being brought up well.

A wise step parent can only ever hope to be a friend to you, that is all.

Hugs, and a wish for resolution for you. You definitely need to be heard in this.
