Hi Lorna,
It must have been really tough for you to be so honest and post something so frank and personal.
Reading your post, I can't help but think you've made the right decision.
I have not been through a separation (married 5 years), but my wife was previously married, so it doesn't mean life ends and that you will be stuck at your parents for the rest of your life.
The toughest time we have been through was 3 years ago, our 2nd child died suddenly aged just 3 weeks old. Our lives just caved in and I have definitely changed from the person I was before, there is a missing spark. Fortunatey we had our eldest daughter, aged 2 at the time to focus on.
I know this is unrelated to what you have been through, but I just wanted to highlight the fact that life does go on, although some wounds never completely heal, things do get better, and like my wife found out - there is probably a Floyd-head toyboy out there waiting. ......In the meantime you have some good friends here who will support you.
All the best
once a year is probably par for the course if you are Sting
