Come the fuck on.
You didn't know the person you're dating expects you NOT to cheat?
You're either socially retarded or the biggest mind game player EVER.
Infidelity seems to be commonplace nowadays and that growing trend scares the shit out of me. I admit I expect a lot from the person I'm dating. Some things yes, have to be learned because everyone's dating expectations are different, but if you truly care about someone, you'll take the time to learn what makes them tick.
I love when my manfriend knows me so well, he can anticipate my needs in any given situation. Yes, it's possible because I've already experienced it and it was wonderful. When I would wake up in the morning, he would turn the shower on so the water was hot as soon as I stepped in. He had my juice/coffee ready as I walked out the door for work. If he took my car anywhere, he would ALWAYS replace the gas. He loved McDonald's but it would literally make me physically ill. If he ate McDonald's, he'd come home, take a shower and brush his teeth. He knew if I wanted my favorite snack of pickle spears, I would always want three on a plate. All that. All those little details. He took the time to figure me out and it endeared me to him which in turn made me want to do more for him.
Consideration and selflessness, people!
I fucking miss it.
I'm a giver. I love spoiling my significant other and actually SHOWING my love not just voicing it. I don't expect what I do personally to be reciprocated, but I do expect some kind of effort/gesture to keep the relationship and the friendship foundation secure and fresh. So yeah, no cheating, no lying, no mind games, no physical/verbal/emotional abuse, no manipulations, no taking advantage of....for me, that's all common sense, but I guess common sense isn't so common after all :/
In closing, stop being a lying, whore and just break up with your boyfriend/girlfriend. Stop with the mind games and let them find someone else.
You can be a douchebag all you want, but go be a douchebag by yourself.
