Please and thank you

I’ve been with my wife for 15 years and have two step children and son of my own with my wife. Was together about 5 years before we got engaged and married a year later and that’s when it all changed. I’ve always believed in being polite and having manners in and out of the house but my wife and step children find it funny that I say please and thank you indoors and when I mention that they should aswell they all just laugh, fortunately my son is following me with often reminders.
I feel like whenever I try talking to anyone they are just on the phone and I feel like I’m a ghost and that my son is the only one who sees and here’s me.
Am I being over the top expecting such a basic thing indoors?
Outside the house they are polite though.
outside of this I feel like whatever I say is just overlooked and ignored and I’m not allowed to tell her kids off or discipline them.
Basically I feel like I made a mistake and my wife’s true personality came out after we were married but feel like I can’t leave because of my son.

If you are truly unhappy you can leave OP and apply for shared custody of your DS.

You might be best though asking &MNHQ to move this over to the Step-parenting section as you'll get responses from other step-parents in there

I'm with you. It's as important to acknowledge those you live with with good manners as it is those outside the home.
It doesn't take much to say "yes please" followed by "thank you" if your partner has offered you a drink and then brought it to you. Every time probably not but probably 80% of the time we use please and thank you and my 4yo is encouraged to do the same.
It sounds like your values are diverging and you don't feel recognised. It might be worth a conversation somewhere neutral to discuss it

Even if I forget on the odd occasion and remember a few minutes later I’d even say ‘oh thanks for that by the way’.
They think I’m posh because of it but I just thought it was normal.
Even my two step kids who are both teens will burp really loudly and won’t say pardon or anything after and I find it quite rude especially when trying to raise a little boy that likes copying his big brothers.
weve had the conversation so many times over the years and my wife just laughs it off.

First manners are extremely important please and thank you are basic and every child should be thought . If you are unhappy OP leave look for joint custody, kids aren't stupid he will grow up knowing you aren't happy it would be a much healthier environment to separate and co parent if it can be amicable. You get one life do you really want your son to learn you stay in a toxic relationship even if you are miserable? Either that or sit your wife down tell her how you feel and ask to go to couples counselling to try work it out x
