Dude, I'll tell you a trick.

Be nice to your mom, Steve and your dad. Overly nice. Unnaturally considerate, polite, make yourself seem generous and shit. Even if it is just an act, just be incredibly nice and try to look good-hearted.

People can't touch you this way. What are they going to do? There is nothing. You can plot and manipulate, say things to get them to do what you want. You can become the trusted one, say to your mom you saw Steve doing this or that today, etc, and she will believe you because you are the good person, you are nice to steve and her. She will be confused, it will make it easier for you to get things happening.

If they think you are putting it on or something, all they can do is talk behind your back about it. If they say something to you about it, you can act disgusted and offended. They will feel bad because you are such a "good person." Will they know whether you being offended was put on or not? Of course they won't. They have nothing on you.

In situations like yours you can't just openly fight and approach people, the battle goes on behind the scenes. It's a battle of wits between you and Steve, possibly your mom.

I'm not saying I condone this kind of shit, but this is one way to solve your problem.
