My parents separated when I was 6 and by the time I was 10 both had met new partners who they have been with ever since (I’m now 50).
DM’s partner is a fantastic person and I’m so glad I’ve had him in my life.
DF’s DW is another kettle of fish. She has a very false demeanour, would make frequent nasty comments about my skin and weight when DF wasn’t around, told me I wouldn’t be getting any inheritance, and is an all-round not pleasant person for various reasons. I’ve even seen her own family looking at her sideways at times. Never lived with them, just would stay a couple of nights ever 2 weeks in my teens etc.
Now NC with DF & DW for many years now (due to her turning him against me) but I’ve just heard (yet again)that he’s still telling anyone who will listen that I don’t like his DW.
Now, I was unfailingly friendly, polite, and welcoming to her even after a few years when I decided I didn’t like her much from about my late teens. I never let it show - I understand that she is DF’s choice of partner and that’s his choice to make, just like I chose my DH.
However, why is there an attitude that you MUST like your parents new partners? That you are a terrible person if you don’t? Surely as long as you are polite and respectful etc then why is that not enough? To be clear - his DW and I have never had an argument, been rude or horrible to each other. I’m just not keen on her, no idea what she thinks of me but certainly enough to poison my DF against me anyway.
We don’t walk into a workplace, club, school, the neighbours and insist that one MUST like everyone you encounter, so why must you like your step-parents?
