Thankful?

I was hoping to have a child, and my SO and I have been trying for a year and a half (at least), but recent issues in our marriage have convinced me that we probably won't last as a couple, and he is much too harsh to be the father I thought he would be. I'm thankful and sad at the same time because there will be no more chances for me to be a mother as I'm getting older, but I would never want to bring a sweet child into this world under the conditions in which I am living. Anyone else have this issue? I will never get to be a mom.
