Okay, I've looked at your post, and I've dissected it. You ask these key questions: **Why would you do this to someone else when you wouldn't want it done to you? **Is it really your problem anyway, and does this make it right? **Does it make you a bad person? **Is it really not your issue at all? I think the first one reveals a fear of hypocrisy. By going through with it, you would, in effect, be setting up a double standard--You can be a mistress, but your man better never have one. It is said the best pillow is a clean conscience. So, my dear, is yours going to eat at you afterwards? The second? To answer, think about it like this: You're sitting at a table with someone you know is overcoming alcoholism. He's been sober for about two months. With complete knowledge of his predicament, would you open bottles of liquor (those which you know are his favorite and weaknesses) and place them on the table between you? After a moment, the smell of the liquor will infiltrate his nostrils, the taste of it will be in the air on his tongue, and sitting there with nothing but you, the table, and the vodka, rum, and beer in the room, he will begin to twitch. The sixty days sobriety he's worked so hard for are three seconds away from being a thing of the past. Now, is his alcoholism your problem? No. Does this make it right? No. What you indeed would be is an enabler. In application, if your friend is not satisfied in his relationship, you'd be supplying an easy way out by the two of you engaging in an affair. And, while it may not be an "affair" in the emotional aspect of the term, it would still be constituted as cheating--no if's, and's, or but's about it. Sorry. With referrence to your third question, considering all this does NOT make you a bad person. Who we are and how "good" or "evil" we might happen to be is dictated just as much by what we think and don't do as it is by what we think and do do. So, thinking and fantasizing about this by no means means you've crossed over to the dark side. Even if you had, we'd still love you anyway. And for your final Q & A, if it involves you, it's your issue. Their relationship problems at present may not be, but if you do wind up sleeping with him before they're officially separated or unless she knowingly consents to the two of you, then yes, it will be your issue too. Please, dear, do not think I ripped into you. I just meant to give replies to questions you raised, and in no way do I think less of you for posing them. Best of wishes, babe!
