Allyn, long distance relationship is quite difficult especially that you already married and still apart. I know how you feeling right now, you have lots of worries and suspicious mind towards your husband. Been there, done that.
Hang on there, be patient, maybe he is just sorting some things out not just for him but for you and for the future. I tell you what, we had quite similar situation before, my husband was always busy with his work, always had an overtime. And its hard because we have this 7 or 8 hours difference in between PH and UK, so thats another issue. And sometimes whenever he got days off, we chatted but it didn't last long because he have something to do, run things out, and sometimes fell asleep because hes still recovering for a shift work. I even got jealous with his hobby...he's a bowling fanatic and once a week he has got to go to a tournament. I even asked him to chose between me and the bowling..lol, I know I was just being silly, but i was longing for him to chat with me even if its nonsense topic.
And since I been here, I realise its not really easy to be in his shoes especially that I got a job myself. I can relate of why he was acting like that..its a pressure from work and lots of bills to pay..hehe
Wait til you get here
I suggest, why don't you keep yourself busy while waiting for a visa? Look for a job? go to a gym? or anything? just be positive Allyn.
