Cheating is a pretty shit thing to do to someone. I’ve not cheated on anyone, and to the best of my knowledge I’ve not been cheated on (although I have suspicions that I have. Probably never know for sure though).
But, I‘m ashamed to say this because I’m not this type of girl anymore, I have been that other girl (the mistress? Skank? Bitch? Slut? I’ve been called all of these names) before. It was all pretty awful and there aren’t really any excuses for my behaviour, or his, although I was extremely young (he was quite a bit older), and evidently the guy wasn’t particularly happy where he was/who he was with.
If you’re not happy where you are or who you’re with you should talk to that person and/or end your relationship. Don’t start something new while you’re in a relationship. Secrets don’t stay secrets for very long, especially in a small town. You will most likely lose friends and gain a reputation you don’t want.
If you’re ever tempted to go after someone in a relationship, don’t. There are plenty of people out there who are awesome and single, and they’ll be someone you can introduce to your friends and family, someone you can walk down the street holding hands with, not someone who you have to sneak around with in the dark, terrified of being caught.
And just imagine, if you end up going out with someone you stole (for lack of a better word), what kind of foundation is that for a relationship?
