I've tolerated my boyfriend's parents for a while now, but I have always suspected that his mother was a JNMIL. My boyfriend and I were having a casual conversation and he mentioned about how his mother made a comment about my "lack of bra" when I visited them for Christmas. First of all, I was wearing a bra, and second of all, why are you discussing my body and my undergarments with your son? I have large breasts and bra or no bra, they're gonna be there and it's something I have no control over. She even brought up that it made her teenaged son(who is almost 18 and not heterosexual) uncomfortable.

I was upset, but I sent her a polite and formal message about how it made me uneasy that she was discussing my breasts and I told her that I was wearing a bra, but, you know, I have big breasts and I shouldn't be body shamed by simply existing as a woman with large breasts. Can you guess what I did wrong here in her eyes? I set a boundary. I stood up for myself. I did the one thing that sets a mother fucking narcissist off the deep end, and boy, did it ever.

The ensuing texts were her telling me that I had disrespected her and her house, and she would NEVER show up to my house like that, but most importantly of all, it showed that I...didn't respect myself. Mind you, I was wearing loose clothing, I spent most of the day in a hoodie, and...I was.wearing.a.fucking.bra. Every time I stood up for myself, she kept throwing insults about me trying to drag me down, but I never relented. She even sent me some boomer meme about a teenager crying that made zero sense, but hey, give her a gold star for trying.

She started blowing up (f)DH's phone, and he eventually answered, and let me tell you, I saw his shiny spine. She told him he needed to "keep his dog on a leash" and he told her he was done talking to her. Obviously, this made her even more upset, and she sent me some threatening texts, and I just kept saying, "K." The one that showed her true colors, though, was, "Have fun dealing with (f)DH, he's your problem now." This woman said this about her own son!

I grew up with a NMom, so I know how this shit works. I told (f)DH to expect flying monkeys at some point, and I shit you not, barely five minutes later, little brother is texting him saying, "I've never seen Mom this mad before, what's going on?" He read the text to me and said, "Well, you called that one out."

A few minutes later, his stepdad sent us a group message asking us to stop(mind you, we had stopped already, and this was just another flying monkey) so I simply replied with, "Maybe you should keep your dog on a leash." Was that petty? It sure as fuck was. Did it feel good, though? Yes, it did. The final message was, "We're blocking you both, don't try to contact us." Jokes on them, because we aren't gonna try to contact them; that's exactly what they want.

Edit: Holy shit, I expected maybe a handful of upvotes for this. Thank you for the awards and your support! You guys are awesome.
