Relationships are about compromise, not re-inventing yourself to make the other happy. If you do that than you'll never be happy for yourself. You both of the make sacrifices and do what you can for eachother, not just for yourselves.
Just be yourself and do whatever you can to be a great spouse. Listen, love, give and be a good best friend. My husband and I don't ask the other to do what we can do ourselves. Sometimes we need help and aren't afraid to ask for it. We do everything we can for each other.
