Can I get a restraining order against my husband’s girlfriend for shaming my daughter about her LGBTQ status?

My husband and I are not together, he lives with his new girlfriend whom he has brought around my daughter since recently coming back into her life. My daughter came out to her father and asked for a pride backpack for school when he asked her what she wanted for school. He took her to the mall the girlfriend was in the backseat with my daughter and she grilled my daughter about her sexuality and why she feels the need to flaunt it and to choose another backpack or they wouldn’t buy it for her. I have not met this woman, nor given my permission for her to be around her let alone shame her about who she is.
