Creating a Healthy Relationship
First you should find out the reasons why and what is going bad in your relation. Try to diagnose the problem instead of placing blame, creating anger.
Like healthy relationships, bad relationships are born, fed and nurtured into becoming what they are. Therefore, in order to fix a bad relationship, you must first look at how you've contributed to the problem as well as accept responsibility for your actions, intentional or otherwise.
Everyone has self-sabotaging behaviors. Whether or not your relationship succeeds depends on how well you are able to identify them, review the reasoning behind them, and conquer them.
You need to adopt some new ways of thinking, being and doing, and are now ready to start putting your work into action. It also means finally taking stock of both you and your partner, and what each of you needs and wants in a healthy relationship.
Try to reconnect with your partner. Always remember you don't need to talk about the past discussions which went through last time and which became the reason of your relations getting bad. Now you have to concentrate on the situation in a positive way.
