You have my admiration

It is an interesting topic, I've been put in the position to be
that guy, and I have to say, I was seriously considering it
Their is the position of "I'm not responsible for someone else's problems", and while there is an element of truth to that, it's not a position I would personally take.
I can put my self in the position of someone being cheated on, I have been cheated on, it sucks, so I certainly strive not to be
that guy.
There are some people who just make mistakes, others who make bad choices, and others who simply don't give a fuck about anyone else's feelings bar their own. It's the latter you have to really watch out for.
