Dude, she cheated on you. What could her excuse be? She was drunk? She liked the guy? He had a bigger cock? (Hell, I got cheated on and my ex said she did it cause he had a smaller cock, which was total bs because cock size is irrelevant).
Your girl is spoiled goods. I'm gonna be the bad guy and tell you that she'll probably cheat again. Maybe with another black dude, maybe with a guy with a big dick. Maybe she'll cheat when you get into a fight to spite you and rebel. But most likely she'll cheat.
Dick size is irrelevant. Black dude is irrelevant. Would you feel better if it was a different stereotype? That the guy was a little dick asian? Does that change the fact that she didn't give a fuck about you and cheated? Or was she taking that cock and thinking about you the whole time? Really now?
W/e your age, this shit is never too old to learn the lesson about cheating. Think of it this way, if you best friend got cheated on by someone would you want them to still be with that person? If you have a stepmother and she cheats on your dad don't you think that he should kick out? You get the picture. Take your sorry crying ass out of this situation and put someone else in it and what advice would you give them? I can guarantee you sir that when that girl was taking that cock, no matter the size nor color, she wasn't giving a damn about you. If she did, she would've said that I have a b/f, husband, s/o, and that would've ended right there. But no, she is a hoe. She wanted to experience sex with someone else and even perhaps a bigger cock. What you need to do is say "bye bitch, enjoy that BBC cause you ain't getting none of mine". No girl or woman wants to be with a bitch boy, so don't ever be anyone's bitch boy. Don't complain or cry. She fucked you and there's no excuse for that shit.
She is only saying that she wants to be with only you because she has nothing and nobody else. I guarantee that if that dude she fucked and her had any sort of viable relationship possiblities she'd be saying things like "we need a break", "i'm sorry, i just don't love you anymore", "i need some space". Bro, do yourself a favor and dump this needy bitch.
Again, I'm angry because I went through the same shit and it feels personal when someone else who seems like a nice dude goes through it. It is like a disease, but time is a good healer. My relationship lasted 3 years, bitch managed to cheat twice. You ask anyone they'll tell you that you should probably dump her. I don't know you, but I swear to god that this girl does not love you, no matter how many times she says it.
And why have sex with someone who cheated? Why do you care if she enjoys it? She cheated on you. She cheated on YOU. This bitch cheated on you sir. Get it, understand it. Does it matter why? NO!
Even if you have a small baby dick, is that a good enough reason to cheat? Hells no. If your dick does not satisfy her then she should break up with you and find someone who is a better match for her, sexually. Same shit if she finds you boring, if you guys are not compatible then she should not be with you and find someone else. But that is never a reason to cheat.
Next thing you know you'll be enjoying those cuckold fantasies. Is that what you want? Do you want to be a cuckold? Do you want black and white bulls fucking your girl while you play with your dick? Cause that will happen. (Okay maybe not the last part, but I'm just trying to paint a grim picture.)
Dump that hoe. I know you may not get it but alot of people here do. Google it if you must, but the 'abundance mentality' when applied to women is gonna help you understand and get past this.
My best advice is to understand that you are not the first nor will you be the last to have this happen to them. If you want to be the guy who is willing to be with a girl who cheated on him and disrespected him, his family name, and his manhood then that is your one choice. Or you can break up with her, say that you can never be with someone who cheated. Tell her she is a great girl and that she'll find other great guys. Move on, do not ever pick up the phone when she calls, cut her out of your life and out of your heart. Eventually you meet someone else.
Your choice.
