I THINK I'M BEING GROOMED BY MY STEPDAD

Okay so basically I'm not sure if some of you remember the first time I talked about my stepdad trying to enter the bathroom whilst I was clearly in it and the fact that he was fully aware of it because he saw me go in whilst he was coming up the stairs. But ever since then I've been really cautious and wary around him because he's always super nice to me and acknowledges me more than my older brother who lives with us. I noticed one time I came in and he was all smiles whilst greeting me but when my brother came into the living room his face was blank and he greeted him normally. Also big red warning sign he's been giving me a lot of money and doesn't give any money to my brother which is really strange. My mum knows that he gives me money and doesn't give any to my brother and doesn't say anything but I don't think she thinks anything of it. The second time he tried to come into the toilet it finally clicked that he was doing this on purpose because I swear that I locked it yet he managed to open it? It sent shivers down my spine. That was a few months before. And guess what? It happened today again. Before going to the toilet, I saw him downstairs in the garden but as soon as I went upstairs to go to the toilet he tries to come in. There is no way in hell that is a coincidence, right? When he tried to come in, I quickly shut the door before he could get a glimpse and screamed NO SOMEONE IS IN HERE and after that all he said was "Okay." Another red flag because isn't the appropriate response supposed to be I'm sorry? When I got out of the toilet, I shouted make sure to knock next time and at the time I yelled this he was already downstairs with my mum in the living room and the door was open so I'm sure my mum heard.

Guys, I don't want to seem crazy and I know if I tell my mum she'll brush it under the rug and say it's all in my head or she'll say it's because I don't want her to be happy that's what she said to me last time I cried during Christmas dinner when I asked about my dad in front of my mum, stepdad and older brother because I was thinking about how my dad would be spending Christmas alone.

At this point, I'm prepared to start shit and confront this guy about what he's doing to me.
