CS 101:
First, I never was a JW and my brief time here has taught me that theoretical knowledge and personal experience are two completely different things.
But I have been divorced for about 4 years now, so my tuppence-worth if it's any help at all.
I was married for 23 years (half my life at the time of divorce). We have two grown-up kids, now 23 and 25. The divorce was very amicable, and it's probably true to say that we still love each other, just not in the way that allowed us to stay married. My job had a lot to do with why we separated.
I think it's pretty normal that when you divorce after many years of marriage you feel a little (or a lot) lost. The former 'anchor point' of your life has gone (and it was easy to take it for granted that it would always be there). The feelings of loss, sadness, and fear of the unknown are, I'm sure, fairly common. When one is recovering from something like the JWs I can only guess how much this would make the situation worse.
But there are positives, too, especially if you can maintain (at least) civilised (and preferably friendly) relations with the ex, and meaningful relationships with the children.
For (perhaps) the first time in ages you have the space and freedom to work out who you are as an individual, not just as a spouse and a parent. Depending on your religious and moral views, you can go overboard for a while and enjoy the 'worldly and sinful' pleasures you never considered before, without hurting anyone.
And when you're ready to move on to a new relationship, which can take a long time, you bring to it a lot more knowledge of life and understanding than you had before. But just a word of caution (from experience) - don't let loneliness, or the enjoyment of a physical relationship, drive you into a lasting committed relationship too soon or with the wrong person. The real feelings that matter in a lasting relationship - love, friendship, companionship, caring, sharing etc. etc. - will surface again, and you'll recognise them when they do.
Sorry I'm not in the UK, or we'd share a few beers (or get drunk in the gutter, as appropriate).
Good luck.
