My boyfriend's now ex "friend" just flipped on me because I politely asked her to take down a photo she posted of our son, without our permission.... um okay. We don't even post him on social media, so idk why she felt it was okay to do so. Mind you she's 5 years older than me, so you think she would be a little bit more mature. I guess addressing something woman to woman is "starting drama."
