world wide heart

so i understand that everyone is different. i understand everyone has their own opinions. i get that everyone has a completely different brain, and also people agree on a lot of the same things. but what i (no matter how many times go over) dont understand is what goes through peoples minds when they reach that point of hurting someone you love, without regret. i was just watching the bad girls club and this girl invited her best friend to stay with her and she says there was a lot of drama in the house that night with the other roommates so to "relax" they drank poison in the hot tub.. obviously they ended up drinking themselves to stupidity like most girls and later on in the morning she called her boyfriend, still drunk, and told him that her and her best friend had had sex. she laughed it off, and that morning said goodbye to her friend because she was going back home. later on her boyfriend had called the house and he was like you know we have to talk. so she gets on the phone and shes like blah blah yea you know i didnt mean to all we did was make out in the shower. being the thank godly man, after her predictable im sorry i love you youre my whole heart i didnt mean to cliche speech.... he was ultimately like its not cool, im not like other kids who likes stuff like this, im a man...i dont look at you the same, its not the same and this isnt gonna work... she starts crying and writin her sob story. my heart usually feels, for everything but i just dont feel bad at all. what really goes through your head to make you think its okay to cheat who you love. to be disloyal to the person youve given your heart to. she even says at the beginning of the episode "cheating is cheating no matter if its a girl or a guy". and as im watching the rerun episode again shes saying oh i am bi sexual but i wouldnt hurt my boyfriend and when i watched the end of the episode earlier she says to her boyfriend im not bi sexual....i know this is a tv show but this cant just be all artificial, and even if it is, people had to get these ideas somewhere and obviously somewhere in the world this has been done with a similar personality that this girl has.. shes not remorseful; she wants to do what she wants to do she doesnt wanna think about what will happen if she causes a tornado in the road of her relationship and she wants her home to be completely made up when she gets home..yea too bad. i honestly cant stand this show, most all those girls are exactly what they try to live up to; BAD girls....... she says near the episode when her friend is leaving "aww all my loves are leaving me"..... guess what, you predicted the future.
