Hi,
I've had a google but am confused.
Looking at the government site, it says there are 5 grounds for divorce, one of which is desertion. Under 'desertion' as a heading it has various options including that your husband or wife has left you in order to end the relationship. www.gov.uk/divorce/grounds-for-divorce
That looks really simple, but when I googled more it said this is a very rarely-used option and it's much commoner to wait two years then file! Er ... really?!
What is the best way forward? Neither of us thinks the other has been particularly unreasonable, and we're loath to go down that route.
