AIBU to already be worried about being a MIL

[FarrahMoan]

DS1 is 11!

Reading the threads on here and knowing my own slightly difficult relationship with my MIL makes me worry that I'll get it all wrong.

So please tell me what are the MIL rules to abide by? (e.g. no stealing expensive corkscrews)

Also is it just the DIL/MIL relationship which causes issues? My MIL seems to get on brilliantly with my BIL's boyfriend

And is it true that the happiest marriages are when the MIL and DIL get on?

I’ve never had an awful mil. My ex mil was bloody brilliant and I miss her everyday. We bonded. She was relaxed and fun and a bit cheeky. Not the same as me but we had enough in common that we became great friends and she would often call me for a chat and just tell me to say hi to her son. She was not judgemental at all and she welcomed me into her family and home.
My now mil is so-so. We haven’t really bonded and I never feel particularly welcomed by her (or fil). She thinks DH is an angel and seems to think I’m difficult whenever I express an opinion. As a result, I tiptoe around the in laws, never really being myself. DH has a weird relationship with them too. They “get on” but aren’t close and I feel like they don’t know the real him.
By contrast, my ex was really close to his mum, a total mummy’s boy but it never caused any problems because she was ace and very secure in her relationship with her son and so didn’t ever feel threatened by me.
