1. Learn about yourself 
To communicate oneself more effectively and clearly, take some time to learn to love and accept who you are.It's detrimental to your mental health to be unable to control or appropriately express your emotions. 
2. Make the necessary effort 
Good relationships are created, not discovered.Commitment and a readiness to accommodate one another's demands are essential components of a successful partnership. 
3. Establish and uphold limits 
Setting boundaries is about communicating to others around you what you value in relationships as well as what you don't want or like in them. Consider your boundaries and communicate them to others; for instance, respecting your alone time.By doing this, you can relieve some of your relationship to make any unrealistic commitments.
4. Speak and Pay Attention 
Disagreements arise in all relationships, and that's okay. It matters how you communicate and interact with each other.Instead of listening to react, listen to comprehend.Talking to someone you trust about your feelings and weaknesses shouldn't be a source of fear.
5. Give up control
Our responses to the events and people we meet shape a large portion of our lives. You'll save time and tension when you realize that the only thing you really have control over is what you do and not what other people do. 
6. Consider and gain knowledge
You can respond to other people's sentiments in a healthy way if you can communicate your feelings in a healthy way. Often, the source of anger toward someone is a location where one is injured and unhappy. Understanding it will help you articulate it and improve your interactions with other people. 

7.Fight fair

Prior to speaking, calm down. If you have the chat after your emotions have subsided a little, it will be more fruitful and you won't say something you could later regret. 
Make use of "I statements." Express your feelings and desires without pointing fingers or assuming any guilt. For example, "You never call me when you're away" vs. "When you don't call me, I start to feel like you don't care about me." It appears that only I am concerned about this relationship. 
Keep your words precise and unambiguous. When describing actions that you find unacceptable, try to be accurate and steer clear of judgment and criticism. Take aim at the issue, not the person. 
Pay attention to the matter at hand. If you ramble on, the conversation is likely to become stuck.
