To want to know my dc will be ok?

[Bleachersinthesun]

I’m about to pull the plug on my marriage and I so wish I had a crystal ball to know that my dc will be ok.
It will be me ending things, so it feels very selfish that I will be causing this pain to my dc. However I’m not doing very well from a mental health perspective by staying where I am and I can’t see it improving.
Waiting for the dc to be older has kept me here but my youngest is still only 6.
Causing them pain goes against everything I’ve ever done and yet it has become untenable for me to stay in this marriage.
I know there are no guarantees but I so so wish that there were.

"They aren’t really seeing arguments because basically DH and I are just living very separately in the same house. That said, we are meant to be going away for a week in August which everyone else - apart from me - is really looking forward to.
I don’t want to go.
DH maybe speak several sentences to each other a day"

This is exactly how my parents were. Growing up with no role model of how to communicate, argue, make up, laugh together... has meant that I have no idea to 'be' in a relationship. Please don't do that to your children. Their 'normal' is so far from what normal should be. You are doing them no favours raising them in such a stale environment.
