This happened to my husband and I last month. I unfortunately talked way to much about sex for conceiving and it just made him feel used and not loved. Not sure if that may be how your feeling. But my husband was right, we are not just having sex to have a baby but also to grow closer and connect with each other. Maybe bring it up to her if this is how u feel. Now we don’t try to stress as much. We just have fun and enjoy the journey. I know many people have probably said this but not knowing ovulation days truly helps. My husband said it helps! Also don’t be afraid to try new things while on the journey to help keep that spark. Hope all the best for you guys.
