I don't know if it is over for you. I do know that there can be no new beginnings without an ending. Everything in life goes in cycles. There is a season for everything. If it's dysfunctional and/or not working, then toss it and start over. Such a painful, but necessary lesson to learn. We hold on so tight to what's familiar because we fear change.
I don't know how many examples I've read on here where completely letting go of the WAS has lead to a resurrection of the relationship at a future time. It does happen. Even if it doesn't, the alternative can sometimes bring unexpected and surprisingly uplifting changes.
BTW, you never loose your family. Your kids will always be your kids. A separation/divorce doesn't change that.
"It is curious that physical courage should be so common in the world and moral courage so rare." -Mark Twain
