I thought long and hard yesterday about replying to this, our situation seemed so very different, but then it did to our close friends at the time too, so if it is odd - so be t.
We were together 35 years and married for 34 of those, we spent almost everyday and night together, both working and playing as well as bringing the family up. We were very very comfortable in each others company and shared the same sense of humour amongst other things, of course we had different interests too.
Once alone after all that time, I found it difficult to settle - now 5+ years on, it has got easier of course.
Also I have a wonderful new love in my life, something I never expected in a million years.
It goes to show, we are all different and no one way of living and loving is right or wrong.
