DH's grandmother has taken it upon herself today to come over and do some gardening in my garden. Would be fine but she only discusses it with DH... I live here too and she's terribly judgemental and makes rude comments about everyone's home so I'd rather know when she's going to be coming by. We have a group chat but whenever she's being sneaky or poking her nose in she only messages DH. She has done it before with our wedding and home move and it really bothers me, what do I do? DH is lovely and doesn't get it. Before I sound awful, she isn't elderly or naive, she's very active and aware and absolutely none of DH's family ever tell her to mind her own business. I don't know how to go about telling her to fuck off and leave my house alone?
