I've been in too many of those types of relationships. Maybe opposites attract but I always seem to attract the drama queen. Of course, the drama is well hidden to begin with but it soon manifests itself. I have a stressful enough job without having to tread on eggshells at home. Now I have a zero tolerance to behaviour like that. I read somewhere that a lot of women thrive on conflict, so even if everything is going well they will throw a shit test bomb in to mix things up. Must give them an endorphin rush!
