Applegran, You might be spot on - for some people, but certainly not for others. We are all different. I don't like the assumption that divorce, living alone or loss of a spouse is inevitably a painful, lonely time. I've been through both.
When I divorced my first husband, I was as happy as a lark, living alone - but not feeling lonely and lost, the way I felt when married to him. I think the loneliest place is being with the wrong person, so I felt as though a great weight had been lifted from my shoulders. Yes, he got the sympathy because I left, but I didn't need it. We remained friends and it wasn't a traumatic time.
When my second husband died, yes, the grief was horrendous, but felt along with a huge sense of relief that his suffering was over. My grief was personal, so I didn't want to talk about it. My dearest wish at that time was that people would carry on being their normal selves, not extra kind/sympathetic/comforting/understanding/considerate - just their true selves. When your world is upside down, the last thing you need is for friends and relatives to start behaving oddly. What you really crave is 'normal'.
I avoided them like the plague, the ones acting weird. I enjoyed, instead, the company of new friends that didn't know I'd just been widowed. Family can try to reclaim you, somehow - as if you've reverted back to a younger age - just when you're finding a new life and identity. I had no wish to spend extra time with those who'd completely misjudged how I was feeling - or projected their own reactions. It's just too much hard work, at a difficult time, coping with their feelings, their assumptions, embarrassment, uncertainty etc.
