Props to Helgaleena for her continued frankness and willingness to discuss the dysfunctional relationships she's lived through.
I'm on record here and elsewhere saying that I cannot imagine what would possess me to try and engage in a monogamous relationship again. I decided almost twenty years ago to seriously stop myself from feeling jealous, and it's proven to be both very difficult and a very rewarding exercise in control at the same time. I think that I can safely say that I no longer feel pangs of jealousy, and my last few abortive attempts at relationships have proven me right. I am not a jealous man (any more).
However: I cannot abide a liar, and once I catch someone in a lie, something snaps in my head that turns me into an obsessive person who will go to extremes to confirm falsehoods as my trust evaporates. To some, this appears to be jealousy, but it's really not. Jealousy infers proprietary rights that I don't feel entitled to, nor do I believe that such "rights" belong to anyone else. Maybe I'm splitting hairs, but I don't think so.
About two months ago, I met a guy who met all my criteria and who possessed all my preferences and we started a 5-6 week thing. It was long-distance, as he lives in the Keys and I'm in FtL about four hours north, so we conducted it mainly through e-mails, texts and Facebook except for two occasions when he came up to visit me. Something happened to make him abruptly change his plans during his second visit, and the "reason" he gave me was an obvious lie: a complete fabrication.
As I really was on the verge of falling hard for this boy (and, despite being 36, he was 100% boy), This both crushed and infuriated me, especially as the sex we'd had the night before was so insanely fabulous: easily the best lay I've had in well over a year. So I asked a man of mutual acquaintance about this boy, and was given an earful of real truth: he's a drug addict and "grifter" (exact word choice) who is, basically, a sociopath incapable of returning my feelings.
This news made me literally sick: for the next 12 hours or so I vomited at least once, sometimes twice hourly. I sent him a very wordy e-mail which he first ignored then did not respond to as requested; a second and much blunter e-mail sent him into a hissy fit that made me laugh to think I'd ever been captivated in the first place.
I made my feelings very clear regarding my "truth requirement" once I started feeling anything for him at all: he just ignored it. Obviously, I ducked a major bullet.
My experiences are mine and unique to me; my responses and mindset reflect that unique history. Do I think that monogamy is natural? I can only answer by saying that it's not natural for me, nor for anyone whom I've ever met with any sex drive whatsoever. I'm sure it's possible, I've just never actually experienced it for more than, say, two years.
