Amazing how many people (me included) met the love of their life in later years after getting divorced. It probably won't seem like it now, but you could end up happier than ever before.
One of the main things is that - legally - no one cares who did what to whom and when.
It's all about what's best for the kids, including staying in their own home and ensuring their lives are as unaffected as possible re lifestyle/schooling/parenting etc.
