Never forget those who gave you distance when you needed love. And it's not revenge but a revelation. You now see that you could have died or suffered anything and they couldn't care. Now you know you don't matter to them except when they can use your goodness without any reciprocation.
They say that the good thing about your worst times is that they show you the true colors of everyone. You get to know your true position in the lives of those who claimed to care.
And you can't afford to ignore the wisdom you gleaned during that time and allow people to gravitate back into your life just anyhow. Or else you'll suffer another round of betrayal at critical times and who knows whether you'll survive this time round?
Life is war and you can't change that fact. All you can do is to make sure you're surrounded by people who can take a bullet for you and save your life.
