When this topic has come up on the boards before I’ve given a blurb of my history. Here it is again:
Serious relationship a little over a year long, we were living together and handfast. We were in an “open” relationship - that is, we could sleep with someone else so long as the other partner was okay with that. I was never interested in being with someone else. He was interested in being with more than a few someone elses, and on a couple of occasions, he came to me and asked, I said it was okay, he went off for a happy time, and then returned to me. The stipulations for me were always that I had to respect the person, and he had to wear a condom.
He went through a bad period - work was bad, he was depressed, money was bad, and so forth. I about burned myself out taking care of him. Then, I got sick. Fever and abdominal pain of a very specific type. I’d had it once before. I knew it was pelvic inflammatory disease, and I knew that by the time symptoms show, it can be very bad indeed, so I asked him to run me to the ER. That was a whole 'nother horror story. What it ended up as, though, was that he’d given me a trichomoniasis infection that had spread into my pelvis.
It could potentially have killed me (I have internal scar tissue from the first bout that almost did), and it most certainly harmed my ability to have a child. And he gave it to me because he decided he needed to have sex with his best friend’s girlfriend, a skank I despised, and possibly with his best friend - a man who’d been trying unsuccessfully to get me in bed for more than a few years. Not just sex, but unprotected sex.
And he asked me why, after I threw him out, I was being so mean.
For years after that, if the subject came up, my immediate answer was "absolute dealbreaker. Asshole can burn in hell before I forgive him.’ I’m more aware now that there are other reasons for cheating, and that a great deal depends on circumstance. Like many others, I’m pretty sure that if it were anything short of marriage, it would be a dealbreaker - slip out the back, Jack, and don’t you come round no more. If my (non-existant) husband were to cheat on me, there had better not be any lying, any endangerment of my health, and there had better be some serious, serious soul-searching, apologizing, and work to fix the damage before I could consider staying.
Oh, and no more open relationships for me. Period. I understand so much better now what I want, and I’m willing to walk away if I don’t get it.
