How about I just cheat on my girlfriend? I feel so close to doing it.
Seriously? Why do you want to cheat on her?
She's boring and doesn't want to have sex anymore.
I know it's tempting to want to cheat.  It's never acceptable to cheat if you are in a committed relationship. If you cheat and she finds out, she will leave you.
I don't know.
I do know, there is nothing right about cheating on her. If you're not interested then break up.
