Pleasee tell me if you would be mad or not 😂

Okay not a rant about my boyfriend. But a rant about a "friend." I have known this girl since we were in grade school. We were neighbors. Literally lived right across the street from each other. Unseperatable every day up until my freshmen year of high school. I had this boyfriend back then, and one day out of nowhere he just stopped replying to me. I go to go over to her house to keep my mind off of it and I see the fuckers car right in front of her house 😂 he cheated on me with my best fucking friend.. my best friend fucked me over. Im a very forgiving person so I cut him off, no grudge held. And I stopped being best friends with her and we went our separate ways. I still kept my peace with her. Didnt have a problem with her like any girl freakin should lol we just went our seperate ways and made new friends. Our senior year, she dropped out of high school and has been on bath salts, spice and heroin ever since. Had a baby right after i graduated. She ended up losing custody of her 2 year old because of drug use and her baby ended up in foster care. We are both 22 years old. And her losing custody is super recent. I work at a hospital with patients who withdrawal, are suicidal or who overdosed. Its my job to help people. We were still in great contact because I felt bad for her. I gave her all these resources to clean herself up and get her shit together by July to attempt to get custody of her son back. She put in no effort but we still talked every day and she was even one of the first to know I got pregnant. My boyfriend and I got into a fight, and she knew about it. She asked me what had happened and I told her venting. Shortly after, she stops talking to me and starts liking all of his posts on facebook 😂😂 usually I do not give one single fuck about who likes my mans posts. Not at all. But one I have a history with her, two she's supposed to be a friend and three I was trying to help her get her son back and she stops hitting me up and trying to get into my boyfriends life. Even messaged him after talking Shit about me. Today he posted something and I have kept my cool this whole time. Even with him telling me the shit she messaged him. It was something as stupid as him saying "what's there to do" and she put a little heart Next to it. Couldn't help but message her and give her my two cents. Again I have no problem with girls liking my mans post. But if I knew one of my Friends were fighting with their boyfriends, you wouldnt catch me dead subliminally liking their shit to get them to notice me. Did I let my hormones get the best of me? Or was it the right thing to do? I wasn't disrespectful just stated how it was funny how she stopped hitting me up the moment she knew we were fighting a week ago, messaged him talking shit about me and Keeps liking his shit.
