@SpaceshiptoMars so everyone can be place in categories mum treats her like a child way younger than she is and DSD has cottoned on to this and she's she lies to her mum because she's dumb and mum will believe her but DSD will talk to her somewhat (not a lot but some). She also tries to give answers mum will want to hear and is usually bang on the money.
There anyone else category which DH and her SF falls into is silent as little talking as possible unless for them to do something for her. Seems to get a little kick out of people talking to her and her being rude and giving one word answers. She tends to let these people talk for her in terms of emotions reasons why she's rude ect. This group for people she does 0 to please.
Then there's me who she talks non stop to. She's never rude to me when we are alone but in a group from the above she tries it, and fails because I will say (that's rude x) and move on.
Both DH and mum do not understand how I have gotten her to talk more than both of them combined to me but I suspect me and DSD talk the same language as to speak . People from the silent group are usually fabagasted at difference so much so it's a party trick almost. She does try to please me (it's not her nature to do this but she tries harder than the silent group) but even then it's minimal iMO ,not that I really want her to, I just expect certain things and very blunt about it. Aka used sanity products go in small bin in bathroom. Wash hair and body ect. She certainly tries to lie to me but it's incredibly obvious and I will call it out. She seems to enjoy this part. Like game play.
So in summary to my essay I assume it's probably what you said - I set my stalls up and stuck to them. It is also nearly killing me. Since one of my stalls is do not hurt any children (not just mine)
I worry we moving from unconscious manipulation to conscious. She can and is utterly charming (iMO) when she wants to be which is a new trait. I don't know why this worries me more. My personality is pretty set so it maybe she's just developing hers and as you said being a teenager, and I'm thinking from my v ridged view point which is your personality is your personality and you can't flex the base personality.
Which as I type it does sound incredibly ridged and foolish. Also congratulations on the hug and the real apology. I have had a few hugs but never a true apology that wasn't ordered by her parents so I have said to not bother until she knows why she's saying sorry or it's a waste of her abs my time. Half the time she has 0 idea and I don't believe she needs to parrot things to me that are untrue... at what age did you get the real apology? (So I can eagerly await the age when hopefully she gets it) 🙏🏻
The best thing I think I ever did as a sm is stopped giving to much of a fuck of what others thought of me as a sm and handled the situations thrown at me as I saw fit. Accepting that somewhere even if I had 0 boundaries and danced the guilt dance someone would still think I'm a evil stepmonster has been enlightening.
Yes I lose sleep because once a idea has landed in my brain it's hard to shake.
