I'm in a situation that's similiar to yours. Me and H have been living apart for the last year, first in different countries, now states.
It seems to me that it's harder to deal when there's a lot of distance involved but like others have said (and will say), much of the advice is universal. It applies to every sitch.
Me: 24 H: 26 2 SS: 7 & 5; D: 3 H filed D papers: 8/2/10 OW discovered: 08/10 D papers counter-filed: 10/2/10 There is no method to my madness
