Hi LBeyond,
I remember your earlier dilemma from
last year ... that was a very sad situation, one where your wife (M) thought she could handle poly, but then it turned out to be too much for her. The thing is, once you start poly, you can never completely put the lid back on that jar. Your marriage with M has been permanently altered, both for you and for M. Presumably, the two of you will remain monogamous for the rest of your lives, but you will never stop yearning for poly, nor will you be able to forget U, and M will always remember that you loved U, and that will hurt M's self-esteem, her feeling of specialness, and her faith in the marriage. You can only hope that in ten or twenty years, things will have improved a little.
I do think your post here in this thread is very relevant, and will help anyone who reads the thread. Especially people who are struggling, they will know that they're not alone. Thank you for sharing your difficulties, I know it can't be easy. As for your wife's veto, I'm not sure you had much choice on what to do. Would you have wanted M to divorce you? I don't think so. So sometimes a veto just is, even if you never agreed to veto power ahead of time, your wife can still put down an ultimatum, and most people do not want a divorce. Even if their marriage isn't perfect, there are many things they love about their spouse, and they would not want to end that. In that sense, the possibility of a veto is always lurking in the background.
Polyamory is not without its risk factor, I think the moral here is that one must investigate the risks as much as possible, before moving forward with poly. Al99's story is an example of when poly works out for the best for everyone -- after certain hurdles are surmounted. Your story provides a counterpart to that -- an example of when the hurdles prove too high, and the consequences of pursuing poly in that scenario. People often hear about poly and think, "Oh awesome! What could possibly go wrong? As long as we (have veto power, and) always put the marriage first ..." Sure you can go back to monogamy if the poly doesn't work, but there is a real danger to both individuals' self-esteem, and to the marriage itself. You can't just blithely forage ahead because poly sounds good.
In your case, M realized she was bisexual, and without polyamory, she would not have been able to explore that. So that is a case where not exploring poly is also a risk. How would she feel in ten or twenty years if she had never given her bisexuality a chance? Sometimes you have to try polyamory before you can really know whether it will work. And in your case, there is a fine balance to be had between the dangers of polyamory and the need to explore one's bisexuality. To be honest, I almost wonder if M won't eventually want to try again, perhaps not in a triad situation but more like a V. If that time ever comes, you will have to decide if you are willing to take that risk, and if you are willing to be one of the two partners who only has M as a partner.
Your case is one in which you, too, were subjected to an unexpected reaction.
With sympathy,
Kevin T.
