i think it suffices that i say these points:
1- whatever happens between u two should stay between u two.. don't divulge too much, lest others get annoyed with the marriage, or get a reason to talk about u, or envy you, or misuse that very information at the wrong time against you..
2- when there is a small fight, don't submit it to your parents.. parents love their children too much that they cant see their fault or allow compromise, and they're not forgiving of something done to their child, so sometimes their advice causes trouble.. (I've trouble keeping this point crisp and inoffensive towards parents.. but this is just something I've had the misfortune to witness some time back)
3- don't think of what you do as giving..understand that and you wouldn't have to work so hard
4- you're married, you didn't suddenly become transparent or your actions understandable..voice things u think about just as when u were courting her (pardon the old-fashioned terminology)..
