Once you let in, there’s no going back!
Life waits for no man, and what’s done can never be undone. You let in another to your life with your own purpose, so if things go wrong you shouldn’t point the finger at another.
Maybe they truly love you, care for you, but if they fail to understand what you desire, then the doubt comes to play. So, always try having a smaller circle, trust only the few who know who you are when you are comfortable being yourself.
Keep close with few people that fully accept you, so you have lesser crap to deal with. Having many friends doesn’t count your trust, but having few true friends does.
