OK, as you know I do have a husband LOL, but I think that you do reach a point when you need different things from life kwim? I know with my Mum, when her partner passed away a few months ago it was the first time she was single since she was 19 and she is 53 because she moved out a dead marriage with my father straight into the relationship with her partner, so all of her adult life has been spent with someone else in it and we were talking about it a little while ago and she said that she just can't see herself ending up with anyone else - not because he was the great love of her life and no one can replace him, but because she just doesn't feel that she needs someone in her life now. But by the same token I know of others who have separated and at the time they needed to be single to regain their identity, especially those that were in long relationships/marriages and once they were confident in who this 'new' person was they were ready to let other people into their life again ITMS.
