She's extremely insecure and passive aggressive. She will never say what she wants but will be upset when people don't give it to her anyway. It's exhausting. The idea of her inviting me over to make Christmas cookies, or even just having a normal conversation with me about books or TV, sounds impossible.
I think she has this idea that she missed out on all the best parts of motherhood because she only had boys, and this plays into this sense of entitlement she has. Like she's owed certain things in life because of the terrible fate of mothering only boys. I think she also assumes if she'd had a daughter, they'd have all the same interests and be best friends. So I never live up to her expectations because of course I am my own person and we don't have that much in common, and will likely never be that close. I'm also not super close with my own mom -- good and respectful relationship, but we're not tight.
So I guess I think you are wrong OP. Some MILs with sons might be like that, but mine definitely isn't. I think a lot just depends on if your MIL has universally good MIL qualities. Is she secure in herself? Does she have good boundaries? Is she thoughtful or kind? Etc. If your MIL is like this I don't think it matters what genders her kids are.
This is also how my MIL with three sons behaves.
