Just that really...... do you spend time with each other trying to get things back on track whilst not living together or is it totally no contact.
I'm assuming you sort out all financial stuff but again how far do you go, maybe sort out separate bank accounts etc but what about assets, property etc.
Do you give/decide a timescale by which you make a definite decision on whether you can make the relationship/marriage work and live together as a couple again or is it as long as it takes type of thing.
