Short, I can really relate. In my M, I think this has been a significant reason we wound up where we are. I discussed this with W when we first started realizing we were in trouble. She said she'd wished I'd told her years ago, that it was perhaps to late now. Looking back, I think the whole HD/LD issue was present before we got married and much more important than I recognized. For me, while I love my wife and family and would love for things to work out, I also feel that I need to be happy too. I hate to be cliche, but we all only really live once and life is horribly short. We (at least me) are midlife before we know what we want, what is important, etc. In that regard, I don't see how one could or should live in a situation that is in a sense, futile. My upbringing and values are that I should marry once until death do us part, but the more I endure this situation, the more I see that- this may not work. I may get D. But life will probably go on and things, while different, may be ok. I just don't see staying in my present situation for another year.
