OP. How traumatic for you and your parents' reaction would of course make it far far harder to process and move forward from.
Just want to echo all of notquitegrownup's post of 13.12.25.
Your feelings are of course utterly reasonable and it's a shame your parents/family have made this so much harder for you, both by their stance and by being so dismissive of your feelings that they've got you wondering if you're the one in the wrong!
Of course you're not remotely unreasonable. But your own reasonable strategies won't break through all this loaded denial they've got going on, sadly.
It was a hugely traumatic thing to happen and the "family rule" of "not upsetting your mother/parents" sounds like it takes precedence over everything.
It's very hard when something comes up that means you have to break the unwritten family rules to protect yourself and your children. Funnily enough, that's when most of us finally feel we can/need to, when we see our children affected. I think your sister would find she feels very differently if was her child it had happened to...
I know I'd never have felt I could have broken the family rules for myself (my mother, very similar, it's very hard and anxiety-provoking even now to face the guilt of breaking the rules of never saying anything negative about her etc, due to her feelings and the importance of not upsetting her always being paramount). It doesnt leave you anywhere to turn when she is actually doing very upsetting things like this, does it?
You've every right to feel how you feel, and do whatever you feel comfortable with. The only practical suggestion I have is to only go to their house in whatever way genuinely makes you comfortable (so only going there without DC or only seeing your parents in other places not their home, whatever makes you feel okay).
And when they question this, use the broken record technique of "We'd love to all come over, when the bannisters is fixed" And when the guilt starts about why they can't do it now just do the "That's a shame," and offer again to have them over instead. So they can't claim you're not letting them see the DC etc, you're offering them that, just waiting until you feel the house is safe for your dc before you meet them in their house.
They may all claim you're unreasonable to feel as you do but they have no right to.
Sorry if all this has been said already, I can't read the whole thread atm but have read all your posts, and I'm really a lurker who doesn't post but it seems wholly unfair that you're being made to feel like this when you bent over backwards and minimised your own distress to save them upset - and then they continue on like this..
And DinosaursRoar,
for you too, so very sorry for your loss and your mother's reaction in the midst of it - glad you have your PILs to show how things should be in supporting you.
