MIL "mum"?

[OrdinarySoup]

This will be short as I'm typing with one hand - sleeping baby in the other!
Since my mother died last year my M-I-L has signed every card to me as from "mum". We are not terribly close and my husband has little time for either of his parents for various reasons. Over the years MIL has been thoughtless and downright rude, but we have sucked it up and said nothing. This "mum" thing has really riled me and I don't think I can keep quiet on it. Any advice??

wow, that is very insensitive, though I hope meant in a nice way, by her.

Next time she does it, could you drop her a text and say that you appreciate the card, but it makes you miss your own mum that much more when she signs the card from "mum". I know it's not true and I'm sure you miss your own mum a lot, but telling her she is overstepping the mark will cause a massive row. If you could solve it without a row it would be probably better for your own stress levels.
Or could your DH have a word?

I'm very sorry for the loss of your mum

Tricky. DP signs his Father's Day cards from me too which pisses me off as my FIL is NOT my dad. I don't know how you would bring it up though.

How did she sign cards before your mum died? It does sound tactless though.

if it was since your own mum died then that is weird and inappropriate

I would have no hesitation in saying something along the lines of "you are my MIL not my mum and it upsets me when you refer to yourself as mum"

MIL used to do this, after my own DM died. I know she only meant well really, but I was uncomfortable with it. Rather than saying anything directly (too raw from DM's death for a long time to approach the subject with MIL tbh) the next cards that went to the ILs were addressed to their first names by me, but to Mum and Dad by DH. The message was obviously received as future cards didn't get signed "mum". It probably would have been better if I'd had a conversation about it instead I suppose, but I just wasn't up to it then. And I asked DH right from the earliest days not to sign mother's or father's day cards from me, too, as they are not my parents.

My mil refers to herself as M2.

I have various names. This is possibly the shortest.

Various names for her I mean.
