You need to take a break from relationships and concentrate more on healing. If you spend the time opening up and talking you can slowly learn what you fail to recognize in the other person you begin a relationship with that turns out where you end up in yet another abusive relationship. I believe you are a nice person, in fact, you are probably the kind of person these abusive type personalities look for. Now you are at a point where you are emotionally exhausted and emotionally sensitive because you have been hurt so much. You deserve to take the time you need to heal and build up better defenses.
