Your situation probably is not as bad as your LG thinks. Try to find out the real reason that he is not happy, he might not like the job itself. If he is just bored, you guys can travel more often la. Have a baby may be a good idea too.

Also I heard you can pay $1000 to rush up green card process. And a lot of friends obtained GC without company's support.

MM should try to find some friends for yourself and your LG. Later when you have babies, you would wish you had cherished more of this period of time in your life. We travelled a lot, went to all kinds of fancy dinners and I was on the phone for hours being friends' relationship consultant...... Each stage of your life is unique and has its pros and cons......
