Those of you who marry younger ladies may find a situation similar to what I am seeing now. My wife spent all her life with her mother and grandmother prior to her coming to America. Now that she has been here for over a year, the growing pains are coming to a head. Having always before been under the protective wing of her parents, Marina is now having a difficult time getting them to accept her as an adult woman, with her own ideas and independence. This "breaking free" process occurs for most people, but it is often a difficult time at best. Combine it with the frustrations of living in a foreign land and depression can easily set in.
I have noticed the deterioration of my wife's relationship with her parents, and I have made extra efforts to be more attentive to her needs. The married lifestyle has also affected my relationships with my family. There is now distance between myself and my sister that didn't exist before. I remember when my father married his second wife, our relationship changed with him quite a bit. I think that this is normal for many marriages, if not most. For those who've never married, be forewarned of these changes.
One thing that has helped my wife is her best friend, back in Iowa. She called Ira and they talked over an hour on the phone. Ira has faced the same exact situation earlier and was able to share her experiences with Marina and give her some advice. I cannot stress enough that you need to build a support network for your future spouses, once they get here. Find Russian speaking people in your area and get your wife in contact with them. Hopefully, when the time comes, your wife will have someone to fall back on when they need it.
As always, this is simply my 2¢ and strictly my own opinion. Your mileage may vary...
