Or maybe they’re not? If you have seen all the evidence of someone’s selfish behaviour with your own eyes but still accept what they tell you as being the truth, are you a fool or are you just willfully ignorant? You think that every person who has been in a romantic relationship with that person is the one at fault and they’re just an innocent victim? Really? Unless you’ve been in a relationship with them yourself you’re not in any position to judge. You have no idea how they treat their relationship partners when you’re not there. If someone has been with countless partners over a long lifetime and all those former partners are all saying the same things, perhaps you should give more credence to what they’re saying and less to what you’re being told by the person who’s claiming to be a victim. All those other people can’t be wrong and this one person is totally free of blame. It’s just not logical or probable. So before you jump to their defence with impassioned and malicious comments, please consider this.
