<human>: Hey reddit, stuff's been happening recently and I'm in need of some unbiased advice cause I'm going crazy and don't know what to do. 

So some back story: My ex (let's call her Lana) and I broke up a little over a year ago after she emotionally cheated on me. She then proceeded to date the guy, break up with him, hooked up with me and two other guys, then went back to the first guy. (Let's call him Joe.) Throughout the relationship, Lana and I have messed around a few times, though she always seems regretful and we never follow through. Joe almost always finds out, they argue, and she blames me.

Fast forward to these past couple weeks. Lana and I messed around again and Joe found it. Lana blames me and breaks up with Joe. She refuses to talk to either of us. I'm freaking out because she's never gotten this mad before. And Joe has the nerve to text me saying how I'm not a man when he did the same thing to me.

Reddit please, what do?

Can you provide a brief rundown of the text in within 3 sentences?
