I hope people can listen to this all the way

listen to the end to what my friend did to me and I want someone please tell me that's wrong because he says he doesn't see it being bad or his fault. My girl less than 24 hours later acted different and never trusted me again and always called me a liar when I kept it so real with her at all times 0 lies and she act like I'm lying the whole 6 months for real. Its not her fault she did that because how does she really know who to believe. She's sitting over here thinking a good friend would never say that and lie so she started believing him. What's worse than a friend since middle school turning their back on me like that?
