Advice is easy to give. It's easy to say that each of us should understand the point of view of the other and be accommodating. But very often these are deep-seated ways of thinking which cannot be changed by any of us. Perhaps the habits of the other can be ignored for a while but they always lurk under the surface and if left unchecked can build up intense feelings of resentment that can suddenly explode without warning.
It helps for both to realize that this is normal and that they're hardly the first couple to go through this. Even that might not be enough. Respect for the other person's point of view is, I think, the key. You might not understand or even accept a point of view that is so vastly different from your own. Respecting that point of view however and treating the other person's feelings, preferences, and emotions as just as valid as yours will probably be the only thing which will achieve a measure of peace between the two of you.
