OK, you've asked a sensible question! 🥳 Are there some things you could do differently, that might help ease your relationship with MIL?
You just wrote: Oh I would love a MIL who came and interfered and helped and made suggestions and chatted and wanted pictures etc etc and cups of tea. I love chatting, I could chat forever about anything.
I have comments; I'll start at the end. I'm a sociable soul, get on with most people and love chatting. But people who REALLY love chatting do my nut in! Conversation with them doesn't feel like a two-way thing, sometimes you truly can't get a word in. They brain-dump for an hour at a time and I'm sitting there wondering if she's even noticed who she's talking at, she certainly seems a hell of a lot more interested in herself than in me.
I know that very matter-of-fact people feel like this about ALL general chit-chat. They need two-way, focused exchanges. They hate being expected to "know what you mean" and they don't give a shit about that time your Uncle Trevor had a similar issue, unless you're telling them straight up that Uncle Trevor found a solution and what it was.
They like direct statements, direct questions and relevant information. Unfocused talk confuses them and wears them out. Sudden leaps upset them - if you're imparting the secret of a perfect coq au vin, do NOT veer off into a description of the magical restaurant in Normandy where you learned it. If they ever want Normandy restaurant recommendations, they'll ask you directly.
"chatted and wanted pictures etc" - eh?? A couple of hours ago, you were fuming that she shared the pictures you sent, with chatty captions! Make yer mind up, missus!
"interfered and helped and made suggestions" - eh? again! One hour ago, you told us "She has tried to force her opinions on me. For example she hated that I expected her son to change nappies because as she kept repeating it’s just more logical for me to always do it".
Don't suppose you asked in what way is it more logical? Have you thought of explaining that (if it is more logical), efficiency isn't the only thing to consider, baby care's a very important factor in bonding between parent & child? Or whatever your reasons actually are, of course.
You contradictory little chatterbox, you ...
