“I do think on Mumsnet people bend over backwards to excuse mothers/Mil's.
Some are just manipulative narcissists.
I wouldn't put up with this shit for a second.”
100% agreed to its the above
She’s manipulating you and your DP. Is it normal to want to see your adult child without his partner/grandchild? Absolutely, nothing wrong with it. But I really don’t think that’s the main point here. For 10 (!) months she’s been avoiding your partner, he’s been trying to contact her on multiple occasions. It’s controlling, narcissistic behaviour, it’s her way or the high way. I also think that OP has every right to feel sad that MIL doesn’t want to see her grandchild. I definitely would.
To be honest, if the roles were reversed (you not liking your MIL) I feel like more people would be saying that you should try to make some effort to see her from time to time, at the end of the day she’s your DP’s mom. Not often but occasionally, during some larger family gatherings. I think it should work both ways, even if she doesn’t like you she should be making some minimal effort and not behaving like a child.
Probably not a popular opinion but I’d stop justifying her behaviour. “But as a mother she has every right to see her adult son on his own” someone said in one of the earlier posts. No, there is no right nor law guaranteeing this, it’s a privilege you don’t deserve if you’re a shitty, manipulative person.
Your post resonates with me because of a similar family situation. After almost 10 years of bending backwards I decided to stop trying with my MIL (very similar manipulation style and passive aggressive behaviour). She also specifically tried to exclude me from some family events, which my DH didn’t agree for; I know how much it hurts). My life has been much better since I just stopped trying to please her. I think if someone hasn’t experienced something similar, they try to give you advice which would apply to ‘normal’ people. But in this instance it simply won’t work. She won’t change. You/your partner will give in once, she’ll keep doing the same thing over and over again. Try your best to move on and be happy. Don’t let her live rent free in your head. All the best.
