My best and boyfriend got into a bad fight because I had ended things with him about a month ago and I would talk bad about him with my best friend since I was so mad at him. During one of me and my friend's conversations about him, she decided to text me saying "What a ******* liar. LMAOOOOO omg I can't believe you just said that 😂😂😂😂😂😂 his cheap condoms are going to break. Omg I want to text him and ask him if he needs those small condoms that don't fit my boyfriend lolol. Since he has a little pecker" I went along at the moment and laughed too saying it was a perfect fit. But me and my boyfriend started seeing each other again and he saw that text message between my friend and I and got so mad and offended. He called her and told her that she can talk **** about how he's a bad boyfriend but not about his personal stuff. He told her she needed to lose weight, and my friend told him that my ex was better than him to me which I got really mad about because that was a horrible relationship and she's no one to be saying who was a better boyfriend to me. My friend also talks a lot of smack about random people and would send me pictures texts and call girls ugly. I didn't stop her and went along which was my fault. She also criticizes a lot which is why my boyfriend doesn't like her 'cause she worries about how other people look. I got mad at my boyfriend too though because he could've handled it better and not go off but I get why he got mad at me and her. I tried telling my friend that it was wrong of him but she demanded an apology from me and didn't see anything wrong with what she did 'cause it was a "joke." she's mad at ME and told me that I already chose him over her. What the heck. What do you think ?

I think you need to walk away from both of them... and learn a lesson from this... like don't go badmouthing people to others... because one day YOU are going to be the subject of one of these rather than the antagonist...

I think YOU are at fault here, not him and not your friend. This is something you do in high School... mature adults don't do this.
