why is happens with us everytime ?

why

Have you ever tried to understand why it happens with you everytime? You meet new people, you talk to them. Bonding over mutual interests, you let your heart slip by and grow fonder towards each other but you don't realise how it will be going to hurt one day and when it does, you start questioning everything that happened over a course of time. You blame yourself, you blame them for things falling apart. Sometimes, it's you, not them, sometimes, it's them, not you and there will be moments when it's neither of you two but the timing.
Meeting them at a time when either of you, aren't in the correct mental space to be together or either of you are with someone else so coming together is out of question. What can be done when either of the above happens, maybe making peace with the situation is the only thing that sounds sensible. Easier said than done, I know it is painful when you search for answers and allow yourself to fall into abyss. With never ending doubts in your mind, it seems difficult to rise above your thoughts and letting the time cure everything seems the only way out because when it happens, it heals you for good.
