I've known my stepdad since I was 5 or so, and he lived with my mom and me since I was 10 or so. I'm 22 now and in college, living with my mom still.

I noticed a few months ago that my stepdad would stare at my cleavage and mumble gross things under his breath when he thought no one heard. I've heard things how about he likes my body and breasts, usually derogatory things like "nice ***." I can't always make out the words, because he usually waits until he thinks I'm not listening. I have two more strange examples I can remember clearly.

Once, after bumping into him to get a midnight snack, I heard him talking to himself about how he liked my breasts. His exact words were: "They look so soft. I just want to put my hands on them." There was no one else in the house when he did that, so I knew it was about me. Plus, I admit I was wearing a thin nightie.

One time I asked him to fix my TV, and when he walked away, I heard him mumble, "Damn, she's gorgeous."

Now that I'm becoming paranoid, I notice him staring more and more when my back is turned. The worst is when I walk up the stairs, and he just... watches me walk up, then talks to himself again. WTF is that about? Is this creepy or just a guy's nature?

I should point out: He's NEVER touched me. Ever. I doubt he knows that I overhear him, because he always waits until he thinks I've gone upstairs to mumble about me or until I go into another room.

I don't want to tell him I'm aware of this because has an explosive temper. And I don't want to tell my mom because she's incredibly stressed out already and is about to be laid off. I couldn't bear telling her this. Worse, what if she doesn't believe me?

And it's not just what he says. It's HOW he says it. There's this weird, breathy, sexual tone to his words. It's disturbing and I can't stand this feeling of not being comfortable in my own home.

Am I overreacting to this, or am I right to be completely and utterly creeped out?

Please help.
