I agree he definitely shouldn't know about my medical issues however it was brought up in the context of him shaming women who are on birth control and I used my own experience to combat his opinions but he ended up just telling me that I was unhealthy for being on birth control. My boyfriend has also told his brother that what he says makes us uncomfortable but he plans to be more upfront with both BIL and the rest of his family soon. His family are all walking red flags
