Hmmm....that is strange. Maybe you could talk to your husband and see if he has any insight. I would definitely say if this continues (For example, 6 months from now your MIL refers to you as "your husband's name and his wife" on FB) see if you could like jokingly include a comment like "I do have a name! Hi, I'm Cherish" and see if she takes the hint. If not, I would try to address it. People can't change their behavior if they don't realize what they are doing might be hurtful or maybe considering you guys don't mesh, she might not realize you could be taking something out of context. So it might not hurt to have that heart to heart. OR it could totally damage things, like my heart to heart did with my BIL's fiance. But I don't regret it because I don't think trying to communicate or understand people is a bad thing. If she isn't capable of handling that conversation, that is on her, not you.

I get it, my fam adores my DH but his family doesn't tend to post anything about me. I just don't think about it much, and I'm always happy when they show they are proud of him and excited about what's going on in his life. Maybe a way to think of it is that she doesn't want to talk about you when you aren't part of the conversation?? I don't know, maybe that's silly, but if you reframe it for yourself that she is trying to be polite maybe it'll make it easier to accept that that's not personal, it's just her way.

I think there can sometimes be an odd dynamic from a man's mom toward his bride. If your partner has always been a mama's boy, maybe she's worried you're going to replace her in his life. It's not necessarily rational, no, but people aren't always rational. She could be projecting discomfort about her changing relationship with her son onto you. That's definitely not fair at all, but not everyone has a high emotional IQ, you know?

Could you do a ladies lunch with her and a SIL if you have one? Try to keep it light and steer away from wedding/relationship topics or your FH in general (though thank her for attending your wedding and focus on any help she provided). I'd avoid bringing your mother or sisters so she doesn't feel 'ganged up' on. Scary and vulnerable, but if she's already sensitive, it could make her more defensive.

It could be a cultural thing, too. People are all so complex!

Personally, as a mother of two boys, I think my FMIL is just ecstatic to have someone to talk about girly stuff with! I think she was also starting to worry about her sons ever having families of their own, so I'm good as long as I'm not a total terror.
