Hoco LGBTQ+ Advice

I’m a mother of 17 yo lesbian. She has found love. It’s very sweet, and encouraging. I couldn’t be happier, or more proud. So far the girl is everything you would ever imagine or hope for. I tease that they’re preparing to be a future power couple. They’re both adorable, funny, intelligent, hardworking and very accomplished. Stereotypical type A. Neither have ever been in any trouble. They’re good kids. This young lady pursued my daughter. Asked her out on her first proper date. They meet for coffee before school. Hang out with friends. Conversations headed in the direction of Hoco together. They both are in high school in the same district, different schools. The hoco dates are two separate weekends. Her gf showed up to her school, and asked her to go with her proper. She brought flowers and everything ❤️ It was so sweet! We were so excited. As a Mom I was touched. She ordered a second dress. As time went on, they had to fill out paperwork with parent signature and a school administrator, in order to have a non student attend the dance. Well... gf Mom freaked out. We were already concerned bc her mother stipulated no social media bc of discrimination, grandparents and college apps being sent in (wtf?). Then she decided she didn’t want my daughter going to her hoco bc of discrimination. BUT didn’t care if her daughter went to my daughters hoco. Makes no sense! There within a few miles. We live in a very small, dense community. It’s like 6 degrees of separation. Gf worked on Mom for a few days, and she relented. Only to turn around a week later, and freak out again. She realized that the kids parents were invited to the hoco “before” party. She doesn’t want the parents to see them going together! What the actual. My daughter and her gf are hurt and disappointed! Her stepdad wants to confront the gf Mother 🤣 Am I wrong to think this Mother is ashamed of her daughter and seriously homophobic? She’s the one discriminating her own kid! I don’t even know where to go from here. I am so frustrated and disappointed for them both. I live in the community, with 6 kids at 4 schools. Her daughter and my son run. We are bound to run into one another, or meet bc of the girls. Yet...I want to punch her in the face. What’s worse is her mother and my husband work for the same university 😒 Thoughts, guidance, encouragement is welcome. Anything else will be reported immediately.
