Wear the guy with the crazy ex. How many people have I known in my life who told me that their ex was crazy, only for me to discover, of course, that the reason that they didn't want me to meet or have anything to do with the ex was because the ex had some vital information which, had I known, well, would have made the person I was with much, much less attractive. I always think that it takes two to tango, um, that whilst the other person person's ex may have some issues and may have contributed or been a contributing factor in the demise of their relationship. That when somebody tells me about the crazy ex, the mad ex, the ex that is just a money-grabbing person, my thought is that they just aren't taking any responsibility within that relationship, not acknowledging or even saying "Look, there were some problems in my relationship and we decided it was best to split." Instead, it suggests that all the responsibility was on the other person, which to me suggests that the person that I'm with isn't very emotionally evolved. So beware the person that says that they have a crazy ex because, you know, normally if they're a crazy ex, you could be the next crazy ex.
