After fighting with you partner you will go crazy, not understanding each other, and reduce yourself to blowing youself away.
You will treat yourself like an idiot, and it can take hours, even days, or even months before you can see clearly - finally apologize before going deep into yourself and admitting that you are really stupid.
Before cementing the trust of love that initially drew you to each other - what keeps you together is sometimes the width of distance or ability to always understand eache other.
The problem is that the pain you cause is somehow affecting you. Because the more you love someone, the more vulnerable you will be to them. The more you fall in love with someone, the more it can make you unhappy. The more you value this relationship, the more likely you will be hurt if it looks messy.
