Called my boyfriend ugly and now a girl comments on his Facebook

Me and my boyfriend got into a fight and I was so dome with him. The argument was me not having time to shower and other stuff and he says he's not kissing me until I shower. I am the lead cook in a restaurant, I'm attending school full time, and I keep our house clean. I don't have time to shower. The last time I showered was Wednesday. And you actually don't need to shower everyday. Its bad for your skin. My doctor told me. So we were fighting and he said he's going to his best friends because he needs to be away from me. So.I could get the last word I hit him where it hurts. He got braces a few weeks ago and is insecure about them so I said "Fine. Ill go find a guy who isn't ugly". He looked real hurt and left. I said all this out of spite. He then posted on Facebook am hour letter a picture of him with braces and said " Guess braces make you ugly". Some bitch commented "Don't you remember I had braces back in the 8th grade. You look wayyy better than I did". And he replied " Yeah negative👎. I'm in tear rn and don't know what to do....
