Upset my mother

Me and my mom haven't spoken in a year. We had our own issues going on. In that year I married my husband. It was kind of quick. We had been dating a little under a year when we got married but when you know you know. Me and my mom are now talking. We've missed each other but when she found out I got married she was upset. Not because she wasn't invited to the wedding but because of who I married. My mom believes my husband is gay and there has been a rumor that he's gay around the town since he was 14 years old. The rumor isn't true and how this rumor started was when my husband was 14, he snuck out of his home to meet with friends. He got thrown into an alleyway and assaulted on his way back. The reason this rumor started is because someone started doubting his story and started a rumor that he intentionally met up with the guy for a gay hook up. A man who was in his 50's. When my mom brought this up I said listen I know what happened that night and I'm not having this conversation with you because it's not your business. She said she's just trying to look out for me and I told her to stop talking about it. My husband's assault isn't her business. The rumor was started by random people who wanted an excuse to victim blame a 14 year old boy. My mom kept trying to talk about it so I snapped and told her to fucking drop it. Now she's upset and hurt and saying that we just started talking and we are already drifting apart again. My dad said I was rude and my mom is just trying to look out for my well being. I love her and want to keep a relationship with her but she doesn't know when to stop
