to make a long story short my husband has had this female friend and they’ve known each other since they were kids. I know before me and my husband were actually dating he was already trying to separate himself from her just because of other stuff that happened within the people they were friends with, all of this happened over 7 years ago. Unfortunately she is a family friend so whenever they have get togethers or anything they see each other she is there aswell :/ anyways , I could kindof tell when I first met her that she liked him or atleast used to & I never said anything just because I didn’t wanna be that person, I am secure enough in my marriage to trust my husband, i don’t think he’s cheating or entertaining her behavior I think she’s just stuck in the past. They had a family event the other day and my husband went but I couldn’t because I had a class so we’d just meet each other there. She ended up also being there and this would be the first time she’s been around him since they were younger without me there. When he got there she was taking videos of them standing next to each other and in every video she tried dancing with him. Every time she would try to get near him he would move away from her. Eventually they were eating and she was trying to record herself spoon feeding my husband his food… yeah. And she would post those videos on her Snapchat story so that’s how I saw before I decided I didn’t wanna go. His mom had told her to stop being weird cause if I was there she wouldn’t be doing that stuff and ig she felt called out because she texted me the photo I have attached, I wanna text her back & say something, but  I don't wanna be rude or start drama. I just wanna tell her I see through what she’s doing and I just want her to stop, I don’t want fighting or us to not get along, I just want her to stop. I don’t want to start things between their family and hers either what do I do? I also have to add that we are american so I am not sure where the “xx” came from

how to set a clear respectful boundary with my husbands female friend
