Relationship question?

[Somebody]

Ok, last night I went to a party. Kind of got drunk and stuff. But long story short I let one of my female friends use my phone to call her friend. Little did I know she went on my twitter and post saying that I was having a threesome as a joke. Once i saw it i deleted it fast because i knew it would probably cause drama.The next day which is today, I got a text message from my ex saying "hope that was fun" and " glad you finally got some." I'm like wtf so I text back saying hope what was fun and what are you talking about. Then I called my ex and said what are you talking about appreantly my ex friend saw my twitter post and said something. For some reason I think my ex is kind mad but won't show it. But I'm curious on what you guys think of it
