My husband and I took a ready-made package of documents here https://onlinedivorcer.co.uk/online-divorce-scotland. Filled them in less than an hour. They sent us and we were officially divorced three months later. It was easy, simple, and fast.
My sister fell into a deep depression during the divorce and has not been able to recover for 8 months. I'm afraid she won't be the same again soon. She loved her husband very much, unfortunately, he no longer loves her.
