Of course, some people like their stepparents, but many don't.
My mum died and my dad hooked up with SM days later, although he denies this. From the day I met her she wanted my dad to be a parent to her DC and to have nothing to do with us. When my mum died, I lost my dad too. SM belittled me, divided and conquered me and my siblings, patronised us, and made PA comments about my mum. My dad once fell out with her because according to him he was sick of her slagging us off.
We have not spent Christmas with my dad since they met, decades ago. He doesn't know his blood GGC but is heavily involved with hers. I was once in his house and her DGC came over and demanded to know who I was and who my DC were and why they were calling him Grandad.
My DH tells me that if he was his dad he wouldn't bother with him at all but I have already lost one parent and so put up with this shit. I am upset every Christmas. He just spent Christmas and Boxing day with them and will see us sometime in Jan, pandemic allowing. Even my DH who is very chilled out and never comments on anyone says that she is one of the nastiest, most ignorant people he has ever met.
Her family get all the good bits and we deal with all the shit. He only shows them his fun, strong side. My siblings and I are the ones that get the phone calls about his health, his boredom, how achy he is, the tears when he is unhappy and gets told to look after him when he is sick.
As a result of this, I would NEVER inflict a stepmother on my DC or a stepfather. I just wouldn't do it. For the last 30 years of my life, I've waited for him to throw us a fish and I feel such a fool. This has scarred me so much and made me think very lowly of men. He is so weak.
Out of all the things that have happened to me in my life this is the worst. It's like being cursed.
