Everyone is asking how Rhianna could go back to Chris Brown. Now, i think she's a special circumstance because she is rich, famous and beautiful, and can probably have any man she wants, but it's probably for the same reason why thousands of women go back and stay in abusive relationships.
If you've finally found someone that loves you, you don't want to let them go. Even if people say, "if he loves you, he wouldn't beat you." You don't see it like that. You see that, you're finally not alone. It's probably because you've lowered your standards to a point that you can see past every single flaw. You feel like you'll never find anything better and this person thinks you're worthy of their love.
I think it probably gets to a point where you'll take abolutely anything you can get, and so what if they hit you if you have someone to go home to, someone to spend your life with. It's just about being incredibly insecure or just at the end of your rope and not wanting to let go of something because it's the best you can get.
I'm not saying I justify dometic violence, nor have I ever been in a abusive relationship. I'm also not coming up with a solution because my level of insecurity when it comes to relationships is pretty astronomical. I'm saying I get why people stay in them, and it's terrible, but the severe level of insecurity builds up to an extreme level and other people see that and take advantage of it.
If you move on from them, you'll be alone and it gets to a point where being alone is much worse than a few bruises.
