I really envy people who have a great relationship with their MIL. I don't, she's absolutely nuts, passive-aggressive and narcissistic. DH doesn't get on with her and does very little to hide the fact that he doesn't like her being here. I am slightly better at tolerating her, but that's probably because she's not my mother. As she gets a better response from me, she's always contacting me and inviting herself to visit. I've tried to gently say I'd prefer it if she arranged with DH. My DH works away all week so I'm on my own with the kids and life is manic. I work and am basically a single-parent from Mon-Fri. She wants to come to visit during the week when she can 'help' me but she doesn't really help and I don't trust her judgement to leave her in sole charge of the kids. I've tried to explain to her that my weeks are so busy I'm really not set up for having people to stay during the week so I'd prefer it if she came at the weekend when DH is here too and there's no work/school to contend with. She's just messaged me now asking if she can come in half-term (no - we have plans) or another time soon when she can be of some help to me (i.e. during the week). I've just replied and trying not to be rude asked her to contact DH and arrange a suitable weekend to visit as half-term won't work. Am I being unreasonable to expect her to contact her own son about visiting? Maybe I am, I resent being used as a go-between though just because she and her son don't get on.
