So to answer your question, I know one.
I know one, too. My ex'es aunt is one. She is very family oriented and brought up her kids with Christian values. I can say the kids have very little tigueraje (just enough to get by and not be taken advantage of ...) They are 19, 17 and 15. Her husband died 4 years ago from diabetes and she has not remarried yet ... to what I hear she has/had some pretenders including a governor of one of the provinces but she kept them away/at distance. She is hard working, working 2 jobs, and providing for her family alone. So I say yes, there are Dominican women that make good wives. Not all of them, but many. As Robert said, they come in all shapes, sizes, colors, and the likes.
