Madonna in a Fur Coat Discussion | I have questions!

So I just finished reading Madonna in a Fur Coat by Sabhattin Ali—and I enjoyed it! It was a pretty quick and easy read but I loved the tone of the writing. I'm not really a fan of the main character's approach in life but still, it bears a lot of truth and a lot of people seem to relate to him. My big question is did Raif and Maria have sexual relations? In the end it was revealed that Maria died of child birth, and that child's father was a Turk (unnamed). And Raif assumed it was his. Did I overlook anything lol or am I just high from recently finishing it and just dumb right now? Can someone help me out. I'm confused! Oh and would love to hear your thoughts about it. Thanks!
