I'm in the UK too. Our sitchs are very similiar, i'm a few months ahead of you. I did teh same as you and asked my H to leave, we separated last month and I have to say, while it isn't what I wanted, it is giving me space and time to find inner calm.
If you want to read about my sitch i've posted in 'piecing' - called all 'hope is lost, help' .
Saffie and Jen_Jam, so glad to find you here and offering nuggets off wisdom. If you have the time I would appreciate you casting an eye on my sitch and offering any advice you can give.
