<human>: Can you give me the gist of the text in a nutshell?

Hi reddit I need some help, this morning my friend Amanda sent me an email telling me that her ex, a drug user and generally unhappy guy, got into her facebook and saw where a few weeks back Amanda had talked to me about what they had been going through and what she felt and I was doing the normal friend thing and listening, as well as commenting back. I have no issues with him and had none till now.

He decided that since I wasn't taking his side or telling her to get back with him that I was disrespecting him, so he took a screen cap of our conversation in an out of context part that when read makes it look like I was cheating on my wife Mindy. My wife visits her sister every now and then and I usually can't go because of work, I spend my nights when she's away playing video games and just generally messing about on the internet. On one of those nights I went to our local wally world and was looking for something to make that night and generally talking to people I knew there. Amanda had sent me a message telling me she was bored or some nonsense like that I sent her back a message that said you should come see me, now she didn't reply to that for a bit, so I went home, once home I sent her a message telling her that I was home alone and that I was bored now as well. Since the messages were close together facebook paired them like they were one message since there wasn't a reply in between.

He screen capped this and sent it to my wife, claiming I was meeting up with her and that I had been doing it for a while. Now I don't know what to do I love my wife so much and I can't imagine my life without her to the point that I don't even want to consider what to do "if". So I need advice reddit I have never cheated on my wife and never will please help!
