I feel for you. I have recently made the decision to separate from my loser husband. The horrible, selfish idiot.
I still have al the logistics to consider ... they're re job, living arrangements, affordability, schools etc.
I am done in but feeling strangely better since I decided for sure. I feel that the absolute worst is over for me now. Thanks be to god.
I don't know for usre what the future holds but it sure as hell cant be as bad as my past/present.
I don't think they twig .. certainly not my 'DH' - to me if you want something, truly, you do your best to get it with the resources/tools/skills you have at your disposal and if they're not available then help should be sought. He simply chose not to have sex with me, not provide the support I needed when I had a near breakdown, chose to interpret as threatening my suggestion that I look at developing a new career path if things don't improve in the next year with current job; the list is endless. Putting his siblings needs/suggestions before mine, not discussing important stuff with me... the list goes on.
I digress, big time.. I agree about others not understanding. I would put to you though, do you need them to? Do you have to understand the major decisions they make in their lives or do you accept them as something they have decided in a rational manner? Hope you don't think I am being cheeky - its just they cannot fully understand your marriage, if you know what I mean. they can only ever imagine, based on their perceptions and life experiences..
You are strong. Listen to your heart. Let your head work out logistics. I hope that this provides some encouragement to you or helps you galvanise your position
I sincerely hope I have not been clumsy in my reply .. my own experiences are pretty raw x
