Mother in law

So about 4 years ago me and thw father in law fell out for about 3 months (I nearly lost my relationship because of it)... I never stopped them seeing their grandchild all through that period of time. Things settled again eventually but I'm pregnant for a 2nd time ( due to health reasons it hasn't been on social media and ive told the people that need to know and thats that) I have the overwhelming sense of not wanting them to know when I'm having my c section because I just have this feeling boundaries won't be respected etc........ I like to keep them at arms length so not sure we will ever have that loving relationship some people have..... Its hard to explain but they are an overbearing family who literally share every minute detail and I've always found it too much, they've kind of always made me feel like I'm not good enough for their son/...... I also think it's true that your mother in law isn't the same as your mum and I kinda want my mum involved but not her. This is more of a ramble than anything but anyone else feel like this no real.fall out but you gwt the ick and don't really want them too involved ?
