Every time your loved one has an emotional breakdown or bad mood, you have to take her in your arms and whisper to her ear: “No matter what you say, feel or do, I still love You.” This will cure almost every problem caused by mind. Unconditional Love is the cure to your relationship.
It allows us to evolve. We have to release all the negative feelings that we carry inside. Lover is the best initiator for you who activates these emotions that you need to deal with. Instead of blaming on the other you should focus inside you to find out what is causing this negative feeling. Talk to your inner-child like parent with a kid. Ask what is bothering him. Give love and protection. Be kind to you and your loved ones.
