If we don’t use the name I would like him to maybe explain to her that it’s our preferred name we aren’t fucking using despite all the awful shit she’s done…I feel v annoyed about it now; my mother has wound me up a bit. My father was abusive and she said if someone wants to use her name it’s none of her business and MIL is being outrageous.
DH was really on my side when she didn’t come to wedding/ sent round photos of me to family members in a bid to get them on side calling off wedding etc (yes, really).
Although it’s just occurred to me that the preferred name has the same ending as another son’s name so maybe it won’t fit as well with them as the variant.
Use the name.
Seriously, it will probably be the best single thing you EVER do in this 'relationship' (with your MIL).
The moment you draw a fucking big boundary with pathetic, stirring, self-obsessed nasty little bullies, the tone changes.
And you need it to change before your children, who it seems you ideally would want her to have a relationship with, get any older.
Why you want this slice of poison in your life, when it's clear she's actively tried to sabotage your family and her son's happiness, I do not know. But I get it's complicated.
One thing however is not at all complicated.
If after everything this utter cow has done, you carry on appeasing, you'll NEVER have a peaceful time of it. She'll push on parenting, celebrations, everything. She deserved to be cut off for the wedding, you didn't do so. You say you walk on eggshells now. No shit Sherlock!
If you roll over and lose the name you want for YOUR SON because of this woman, you'll end up hating her even more.
If you carry on rolling over on very big issues - she will never ever get easier to manage.
There is only one way to make her easier to manage and that is to stand up to her. No eggshells. A very firm - if you don't like it - there's the door.
She won't use the door, because she wants to be in your lives. That's YOUR GIFT - take that power. And use it to shut her up.
Use the name. Tell your H that she's lucky she wasn't cut off over the wedding, you've forgiven that, tell her now will be her turn to get over something. He goes in to bat. You have the name you love. And MIL can learn, finally, that you don't create good family relationships through bullying.
