The definition of "standing" accepted by most people here, including RCR does not allow sexual dalliances. How you choose to conduct your life, though obviously, is up to you.
I have always been honest about my sitch. I have had a lovely FWB arrangement for over 1.5 years, since six months post BD. But, I understand myself to be a rare woman who can separate sex and love and I am liberal enough to want to. I have sometimes considered myself standing in spite of that. I feel like all has to be fair or I wouldn't even want him back--if he was able to go off and have an affair, and leave me for her--if he ever got it in his head that he wanted back, well, he would have to accept that I didn't want to be alone while he was setting up house with some other person. That's just me--I considered my marriage over on BD, so I never felt I had anything to be ashamed of and I did not ever believe I violated a promise or hurt anyone by doing what I did. Only you can know how would feel, but do take enough time to be sure, living with regret would suck...
However, I know now that I am no longer standing, and my FWB arrangement is ending. It is two years, the divorce is final, exH is remarried and I want to open myself to the possibility of something real. Dating sucks, but I like being a half of a couple, I just do, I want to go to parties with other couples--I don't get invited to them anymore, and I hate that. I also love to cook and entertain, and in that regard, I can be a great asset to someone who appreciates that, and my H never did.
Anyway, that's all stuff to put in my thread. I think if you go that route, you would not be considered a "stander" here, but you have to do what's right for you. And I get it, for me if was about sex, not love or even companionship, though I like that too, and my FWB really probably is my best friend, but at the heart--it's about sex... That was never the part of my marriage I considered sacred, just the bonus!
The best thing about banging your head against the wall for so long is that it feels so good when you finally stop...
