Different Meanings for Different Beings?

Cheating has different definitions for almost everyone. What one person considers completely out of line and unforgivable, the next may see as absolutely harmless. I’m touching on this subject because it’s something that has changed me emotionally, mentally, and spiritually over the years. I no longer have the tolerance for it. I once was a person who would give endless “second chances”. I can’t do that anymore. Back in the day, you knew someone was cheating when someone was calling your house phone, and your S/O couldn’t seem to talk to them while you or anyone else was around. You’d find telltale signs here and there; on their clothes, in their pockets while doing the laundry. Then cell phones came out, and it was a little easier to do your dirty work. Because then you could be away from your home, but still reachable. And there was no proof (unless the person had the advantage of physically going to where you’d said you were) that you weren’t in fact at said location. Big step number three was the internet. Then came the dating sites, the social networking sites, email, and countless other ways to communicate with the outside world. And every single one of these could be password protected, or manipulated so as to portray a different person than the user was. You could be anyone you wanted on the internet. To the stranger on the other side of the screen, you could be a size 2, blonde, busty supermodel. You could be a tall, dark, muscled-up millionaire who says all the right things as long as you’re right there with the keys beneath your fingers. And unless the other person was willing to do some digging, they’d never know if you were spoken for by someone else.  

   It’s really sad. Honesty is a thing of the past. Being faithful has gone out of style, and the borders of appropriate friendships and conversations have been stretched so far they’re unrecognizable. Some would say as long as there’s no sex, there’s no foul. Stricter people would say no physical contact at all. Then there are the ones like me. The ones who firmly believe that if you have to lie about it, hide it, delete/change it, etc., then you’re most definitely up to no good. I would never approach another man in a sexual manner. Period. I do not flirt. I do not have inappropriate meet-ups and conversations with men. I would never even entertain the idea of having someone on the side.  I have male friends, and they all respect my relationship. I expect my S/O’s female friends to have the same respect. If I don’t know you, there’s no reason you should be meeting up with my S/O late at night, alone. I don’t give a damn what the reason is. If it’s that bad, call the cops. No female, aside from relatives (and a VERY select few) should be alerting my person that she’s home alone and ask what he’s doing. Personally, I find it disrespectful on her part and his as well, if he doesn’t correct her behavior. Let’s be clear: I will stand by my man through his troubles. I will help him any way I can, and encourage him to do/have better for himself. What I will not do under any circumstance is FIGHT OVER MY MAN. If there’s another female in the picture, she can have him. I have too much common sense and self-respect to play along with that. I will cut my losses and carry myself on to bigger and better. 

What are your views on cheating? What do you consider “Eh, no biggie”, versus “OH HELL NO!!!!”? Does anyone believe that a cheater can change their ways, or is a cheater always going to be just that? At what point do you go from "We can work this out", to "Get your shit and get out?"
