When communicating with your partner, practice active listening. Be completely present. Never engage in a conversation just for the sake of hearing and respond with your fixed ideas.
Some chose to know or be aware of the information. Comprehend the whole message that your partner is conveying. Comprehend means understanding in detail and also measuring your partner's thoughts and feelings about the conversation.
In a conversation, when your partner shares with you a problem, stop criticising or giving negative feedbacks everytime. Take the efforts to understand, structure your words positively and explain to them why you agree or disagree. At times, you just have to listen.
Feel....feel....when you are talking to your partner. Always put yourself in their shoes. Be sensitive to their thoughts and feelings.
If you did not communicate well, improve speaking better and effectively the next time. Reflect on your areas of improvement and work on it. Discard dysfunctional interaction patterns.
Start practicing these for a happier relationship.
