Have been there.
2 weeks between returning after engagement and wedding, and then 4 months between wedding and getting visa/reunion in the UK.
It's absolutely, positively horrible.
It's so incredibly hard.
I think just knowing that it IS hard and it's hard for everyone helped me the most. We used facetime and skype calls daily, sometimes hours a day, even just to have background noises. We ate meals together over facetime or phone. We watched shows together on Netflix using rabbit. We had lots of fights (honesty time).
It's soooooooo hard but most of us have done it. I thought of it as our trial by fire...if ever we proved our love for each other, it was by fighting to stay connected while apart. Didn't help that we were both moody, depressed, hopeless, etc. by turns during the wait. At least we were able to sort of alternate our desperately hopeless moments...when one of us despaired whether we would ever be reunited, usually the other one felt more hopeful and could be encouraging.
If your husband can't be there emotionally for you because it's too hard (if he has to disengage because it's too painful for him to connect with you while so far away), come and vent here. Are you going to the midlands? There is a FB group with lots of us who have been through it. Other similar groups too, I should think.
Hugs.
