Perhaps I'm going too global here but it's not just your D. It seems like more and more the world has just decided that the norm now days is D and you don't stay together. I've watched the married at first site series as while I'd never do it in a lifetime, the concepts are interesting to watch - how love is a choice and M is hard, hard work! The thing is, one lady wound not even try for more than a week - never mind the six weeks it's supposed to be, she was out after a single week! Another had a fight and she moved out three weeks in. Just ran away - while still saying she was committed!!! Even these people who claim they want M more than anything are out at the first struggle. That's just how the world has gotten. It is so sad but even more sad it's not just you D. She could very well have parents and grand parents still happily married and still have these feelings. And you will help her raise a child - yep that's right out of today's playbook as well.
So I'm likely not making you feel better but at least know it's not you or what you have done - it's way more wide spread than that.
