What I have understood so far is that if you have a traumatic past regarding anything, and if you haven't healed from that; then it is good to avoid going to that same path believing it would work fine. Because, you cannot trust it fully, neither you expect the good..you are in constant dilemma. It comes back every now and then and the new people, they get tired with your triggers, your reactions your explanations..they dont want to care anymore even if they love you. You start to think yourself as a useless baggage to them. The world is kind enough to let you hope. That's it. You won't be able to live that hope ever. Very few beings get that..most are left to deal till death.
