I agree with MrsMcX, the sex is not the issue, it is the depression.
I suffered from depression last year which was brought on by stress at both work and home, at the time my wife's father was ill, and her mind was on him and her mum, so much so that I felt she had not noticed how I was feeling.
Because she has a history of depression herself, I felt that I could on burden her with how I was feeling. In many ways she sees me as her rock, and I think went into denial that her rock was cracking. I don't think she could accept anything was seriously wrong, even when my GP had signed me off work.
The worst part of being ill, was that I lost all confidence in myself, I even thought that I was useless at the job I have been doing for nearly 30 years!
Anyway, I lost all me usual high sex drive, any attempt to spark me into action, just made things worse. There is nothing worse that being reminded that you have lost all interest in sex.
I found that best way out of my depression, was to deal with the causes, my work were great in reducing my workload and I took a step back from some of the other things I was doing in may life, to give myself more time for myself and my wife.
I most inportant thing for me though was being able to talk about everything and anything with a friend who was removed from my circumstances. This made me understand that I needed to improve communication with my wife. Though it all I also realised that having to deal with my own, stress and depression that I could she how much my wife's issues were impacting on me and the family.
She has had a fear of travel and will not go outside her comfort zone. She hates it when I have to go away for work and will stay at her mum's rather than stay in the house with me not being there. Having got over my depression, I can now see that not only was she being held captive by her fears, but to a degree so was I and our family.
After nearly 22 years of marrage, I recently decided that I needed stop avoiding the issue. I know that my wife will not deal with the issue unless she accepts there is an issue. I know that at times I want to go places and I would like my wife to be with me. I am going away for a couple of days at the end of the week. My wife was not at all happy about it, I explained how I feel, and as is often the case, she went in to a sulk and told me all the reasons why I should not go. This time I did not back down and on Saturday evening she, she told me that she is going to seek proffessional help with her fears.
I know this is not the end, but hopefully it is the start of a journey that will see my wife released from her fears.
Sorry I went on a bit!
So anyway, I would encourage your wife to make friends in your new location, hopefully her new job will help with that.
But also you need to make sure that you look after yourself. It took me having a minor breakdown for me to deal with things that should have been sorted years ago, I would hate for you to get into that situation.
Find time for each other, and try to communicate on a deeper level.
I am now looking forward to doing thing with my wife in the future, rather than treading on egg shells.
