Graduating and the future

So I just recently found I had to attend graduation. I am in what is called a "traditional rotating internship". Even though I am a psych resident, signed up for a year of doing, basically everything.

I was going to attend anyway since I wanted to say bye to everyone before I moved across the country, but as a guest. I mean I just finished 1 year, what is there to celebrate anyway? It was a pretty cushy internship too. I mean internal medicine sucked with it's 6 calls a month, and working 5:30am-6:00pm, but the rest of the rotations were very nice.

In fact, I am more worried than anything. I have had it so good here that I am scared that I will actually have to work like a slave for 12 months instead of only 3 months. For those who read my first post, I'm not sure I trust my wife to keep the household running while I am working. I am somewhat optimistic, since I will be doing what I love and with any luck my wife's hormones will stablize somewhat.

Some more info on my family. My wife is an international. Before she married me she was a up and coming civil engineer. Her English is not very good, so she depends on me to translate many things for her. The trouble arises when I can't quite get the translation right because my Chinese is only at a grade-school level. Given her past level of acheivment it is understandable she is frustrated, and she often vents that frustration on me. I don't really like that, especially when I'm the one is doing everything. I often just tell her: "pick up a book and look up the vocab, I won't be next to you all the time".

I often can't get the thought that she is useless out of my head. I know it's not right, she did raise my son and about to give birth to my second born but why doesn't she try to make herself more independant? I would not fault her for at least trying, but shutting yourself in the bedroom is not making progress. She doesn't work, she doesn't do any chores, she doesn't cook or clean, she doesn't even say thank you. I would not mind doing anything for my loved ones but I would like to think my loved ones...... well loved me in return.
When we fight, she often tries to "teach me a lesson" by not doing anything and make me do everything. I find this laughable since I AM doing everything already, and the only lesson I am learning is: "I don't need you" "I can do all everything without your moodiness".

I will be working harder as a second year, can I trust my wife to do what will be required of her? Doctors have a 80% divorce rate. Everyone tries to beat the odds, but the statistics are what they are for a reason. If I didn't care about my son's happiness I'm not sure I would still be with her. But my son, he is my preious, and his smile is the only thing I have faith in anymore.
