It is important communicate directly, clearly, and honestly. Sarcasm, manipulation, and passive aggressive behavior have no place in a truly healthy relationship. Say what you mean and mean what you say. Don’t criticize your partner. If they say or do something that bothers or hurts you, express your feelings about it. For example: “When you raise your voice at me I get scared.” “When I am speaking to you I sometimes feel you aren’t listening.”
These were just a few tips that could go a long way toward improving your relationship.
