Don't do it!
My parents stayed together, partly for us, and partly because of how the rest of the family would react (religious, certainly wouldn't disown or anything but be very upset and make a big deal out if it).
Now finally they are talking to us about separating as youngest sibling is going to move out in the next 6 months to a year.
At times my parents were a bit unstable, I suspect nowadays it would count as physical and emotional abuse and I think a lot of it stemmed from their unhappiness and poor mental health. I never got over the shouting and screaming and crying either, or the periods of cold indifference.
I love my parents very much but I am angry that they didn't divorce years ago (when one of them used to threaten it in their rows when I was a child I used to hope for it!)
I have never, ever, had any sort of relationship (not even a pre-teen hand holding "boyfriend") and I am not sure I ever will. I'm not very attractive, so it's not like I'm fighting men off lol, and I really struggle to trust someone to that degree
