"How to solve your relationships problems?" ... Most people would answer "talk" or "understand each other" but before we go to that process, I'm pretty sure we have to do one more thing first. Let's learn to "stop" for a moment and and forget the problem. Think of positive thoughts even just one minute and ask yourself, "Is this anger, anxiety, burden, madness, jealousy and everything bad I feel weighs more important than the joy we can have only if put things in right places?".
It might sound easy but trust me, it's pretty hard specially in third party issues. This is not only attitude, it's also a skill.
