I just fear that my STBX will suck me in and I don't have anything to hold on to.
Dont' fear getting sucked in again. If you do you will be able to get out. So what if it takes a couple of more times. You will survive it and you will get stronger. Look at what you have already accomplished. You have figured out that he is bad for you AND you have figured out that someone who makes you feel good is bad for you. You have terrific insight. This insight is working for you in very dark times of your life, in a very vulnerable time. You have more strength than you realize. You can handle this and you will and though you will go through some difficult times you will emerge in a much, much better place.
