Just because she thinks not loving you justifies cheating on you, doesn't mean it's actually justified. I have little to no respect for people that string others along knowing the person loves them and come up with dumb excuses to cheat. There's no good excuse to justify cheating. No one deserves what she pulled and I hope your heart doesn't harden over a person like that.

Sorry that happened to you. I hope the next one treats you better. And this isn't a uniquely girl thing. Both sexes do it. There are shitty confused people on both sides. Honestly, if she's this way now, she's probably saving you future headaches. Imagine having to deal with this over and over with her.
