When is Cheating on Your Mate Really Cheating?

Let's just get right to our title question: When is cheating actually cheating? In other words, what conduct qualifies as cheating? I don't think there's any solid answer that would apply to every situation 'across the board'. This has been, needless to say, a much explored issue. I'd just like to give my thoughts on the matter.

In my opinion, it depends on who you asked, and when you ask them. Whatever opinions one might have when they're not in a committed relationship (or if they are, everything's going well for them), that opinion will likely change when they're being cheated on. I've also noticed that people are often a lot more open on the subject of infidelity when they are in fact the one who's cheating.

Some say that it's not cheating unless it becomes physical. Others believe that physical contact is ok as long as it's not 'actual sex'. So then, is a kiss ok as long as it goes no further? Having romantic or sexual thoughts about (or sexual chat with) your internet 'buddy', even though you may never actually meet in person? Some religions teach that if you so much as desire another person in ANY romantic way, it's the same as having sex with them, therefore (keeping within our subject line), is cheating. Although, I think that's a bit much.

Ok, enough with popular belief, and oh yeah; sorry for the religious reference- no harm intended. Here's what I really think. Take a look at the statements below:

You engage in conduct or romantic/sexual activities that cause feelings of guilt.
You conceal things you do because you believe or know your mate would think you're being unfaithful if he/she knew about it.
You're unsure about whether or not you're cheating.
You want to be open with your mate about a certain 'friend' or platonic relationship, but you're sure your mate will freak out.

In my opinion, if ANY of the above statements apply to you, you're probably cheating. Forget about what anybody else in the world thinks; like I said, there are a lot of general opinions on the subject. This is about you and your mate. I think that deep down people usually know when they're being unfaithful to their mates, but try to find ways of justifying their actions.

Even if according to one's belief they ARE NOT cheating; if you think that your mate would disagree with you, then, in some sense or another, you are probably cheating, even if only on an emotional level. I said earlier, these are just my opinions. But, did I get you thinking yet?
