My FIL and I went through a V tense time about 7- 8 years ago- both husband and I are NHS doctors- I work 40 hours a week during term time (about 30 during school hols) and my husband looooonger hours. We used to work the same but I, by choice, cut back once we had our boys. I only explain this because I think much of FILs initial confidence in passing comment/ judgement came from the fact that I work ‘part time’ (less than DH if you don’t count mum as a role).
In laws visited when my boys were toddlers. We are about 500miles away so contact is always a visit for a week, when I host and entertain, a few times a year.
My FIL pissed me off over a number of low key things before we had children. Minor controlling things but nothing to get too upset about or create drama. Retrospectively he behaved like a dick at times.
One visit to us about 7 years ago (with Toddler and baby) he pushed me over the edge… he was over policing my toddlers, then rebuked me when one little one whacked the other and I pulled boy 1 (gently!) up on his behaviour. And expected dinner on the table by me etc etc.
I had not long got in from work one day and still had my ‘confident work head’ on. I literally hissed in his ear ‘these are my children, you are in my house, you are a guest here and do not impose on my parenting here…’ FIL sat down in shock and was quiet the rest of their visit. I was a quivering wreck after my stand up moment 😂
It was awkward during that visit but he heard it. He must have reflected on it because the suffocating paternalistic behaviour just dissolved.
We have an excellent relationship over the last few years and value each other a lot these days.
FIL still acts like DH is the messiah at times but then he is his father- and we all feel this about our children regardless of age…. Since I had my truth moment with him I think he gets it more. Now he is nothing but warm and respectful to me.
I don’t know that my sisters in law (wives of DHs brothers) get the same. They haven’t pulled themselves up to their highest height and hissed threateningly in his ear… yet!
I think there is a huge generational thing about men/ masculinity/ roles but a good man, irrespective of age, should be able to accept a reality lesson and change their behaviour.
My advice (based on my N=1 experience) Be brave and try to put your foot down OP. How he responds will tell you what kind of man he is.
