Step mother, problem, what should I do next? Please help

I have been contemplating whether to write this up for a long time now for a second view on my situation. But I feel that enough is enough, so please, offer me some advice-I will really appreciate it.

I am 16 and have had divorced parents since I was 2. By parents get along so well for my sake, and have a long history since they were kids, I am very grateful to have them be so lovely with one another for me. I have always felt fine with their divorce. But, they both remarried and with my step mum-well she is causing me problems.

To put it simply, it is not just because I am me that she makes me feel frustrated, she has bad history with mum. In short, she cheated on her husband with my dad when my mum and dad were married and her husband was my mums brother(but don’t worry too much about that as it is confusing I understand). So she has always hated my mum.

Now back to the present, why is she making me feel frustrated? There are a few reasons which, respectively, are not as bad some kids have got it. I know. But this is what I am having to put up with when I am at my dads. And it is so upsetting as me and my dad get along so well-he is like my best friend.

She acts envious of me, for example she has never(I swear on everything) never given me a compliment. I am not desperate, for compliments. To be frank I could not give a shit. When we went out to some snazzy gown and bowtie event(so everyone dressed up formally) I didn’t get anything off her expect a cold look up and down. Yet I say she looks stunning(white lie but I am trying to be courteous). Second one, I get my hair cut and have a salon blowout. My dad gets a haircut the same day and she says he looks like beautiful, handsome and that bollocks, and just walks past me. When my dad asks why she thinks of my hair, she replies “troy(my hairdresser) cuts hair alright”. I’m 16 and she is 45, maybe something little would be kind of nice. Anyways these are just two that I am going to bother writing.

Another reason to as to why I don’t like her is that when I began my exams, my dad gave me this tiny room upstairs to be my study. Instead of respecting the fact that the girls got to get the grades and make her way in life, she throws a 5 day long fit about how she wanted it be her own dressing room. This just upsets me. I mean- am I out of line to think that it is a fairly unreasonable?

Ok so I will leave those two there as my, I could go on unfortunately.

You may be thinking, hang on if you are so ‘close’ and best-mates with your dad, why is he not doing anything about this? Well to be fair I have never explicitly said anything, as I did once(very very subtly) and he said(quite diplomatically) “thats your mother talking” and with my dad he doesn’t like to cause too much agro or trouble so I have a relatively strong feeling that he may just talk to her and this would not do much but make her aware that she is getting to me(a kid) and ruin my years of work of hiding my feelings behind a smile. Also she is literally a gold digger. My dads parents both died of cancer within 9 months of each other and two months later she is begging him to buy a hot tub- why?! Leave him alone he is probably hurting deep down(though he never shows it-bless him) My dad and me box a lot and she always complains like “oh you two are going boxing...again...I guess I will just see you tomorrow then” , “i feel like you don’t give me much love when thats all I give you”.

Finally, you may think well why don’t you speak to her? And I have thought this, but I cannot. I am so scared to and I just couldn’t, I just couldn’t. I can’t.

So, I am thinking of finally sitting down with my dad and mildly telling him this, I cannot live my life in my home like this anymore. But then, I could just keep the peace and just wait it out another 3-4 years until university. She does act like she cares, but it feels like a Disney step mum(two faced as fuck).

Which one should I do?

So sorry this is so long, I just summarising it as best as I could.
