Ellexoh, and any other straights (like myself) trying and hoping to make their Mixed Orientation Marriage 'work': we need to face the stark truth that there are not many 'success stories'. Most MOMs fail, end in divorce. The statistics are there. Lesbian partners/wives are often already in a relationship with another woman when they 'come out' or are found out, and there is some evidence that successful long-term relationships straight man/lesbian are rarer. I've found (on web fora) very few men, two or three only, in my kind of place. Bi or queer men with straight wives seem to have more success.
But what is 'success'? My wife came out to herself and to me four years ago now, and we have since been in a sexless marriage, since she has and can have no desire for me. But we still love each other, have cuddles and touching, some kissing. She is content with this. I am resigned to this being the best that I can hope for, and hope (and pray) that at some point I may be able to move from resignation to a greater sense of peace.
I do, personally, resent those on web fora who say that my wife must be cheating on me. I know she's not. I know that we have total trust between us, and that we both want to go on together. That shared commitment is probably the most important part of staying together.
We have said to each other that our marriage vows have changed. They now read, 'until death do us part, or until one or the other meets a new love of their lives, but neither of us is looking'. If that makes any sense? For me, that permission that I could still find a new love is a great safety valve. But the fact is that I'll be 70 in a few weeks, and my wife is past 70. So there's a strong element of realism in us both: it's too late to make new lives. We're both best of making the best of what we have together.
Warm regards to all, Andrew (Brassyhub)
