What would you do if your spouse stopped talking to you and refused to answer any questions?

I have been married for 10 months and the past month has been hard. My husband has stopped talking to me and won't tell me why. He says he just doesn't care. I don't understand what has happened and am frustrated. We moved overseas a few months ago...in doing so, I sold my home (owned before married), quit my job that made over $100K...for his career. I don't know anyone in the new location. I don't get how he can be so selfish and refuse to work it out or give me the time of day. I don't currently have a job but am looking...however, I feel like taking some time (a month) and going back home to see friends and family. Should I do this or am I abandoning my husband? I just need a break from the isolation I am feeling. Additionally, this is embarrassing but I have caught him several times mmasturbating..before he stopped talking to me...our sex life was perfect. I am over 10 years younger than him and he has been married twice before. What was I thinking? Any thoughts?

Oh...and we were together for 2 years before we married. He absolutely won't get counseling...I suggested it might be helpful. And, I am starting to feel some depression over it all, but am trying very hard to remain positive. That is why I feel I need a couple weeks away...but maybe it is selfish. I am really conflicted over this...I know that I will get some counseling to work through it all...even if by myself.
