<human>: Today I read a message that my wife sent another man. Telling him that he looked cute today in the uniform that he was wearing. I am in the military as well and I guess he felt the need to tell his fellow battle what was going on since he knew she was married. He sent me a picture of the message and told me she had been flirty at work. (Wife is a leasing agent and he is a tenant in those apartments). I know this isn't that serious, but just a month ago I caught her staring at a shirtless guy (almost drooling over the guy) for an uncomfortably and noticeably long time. She cheated on me back when we were dating and claims that it is different now since we are married and have a son, that she will never do that... The message I read today is making me doubt her claims, though. I am not perfect, but I have never cheated on her or betrayed her.. 

I am seeking some advice since I don't really have any friends to talk to... I work alone in my office and the rest of the soldiers are higher ranked so I can't really form relationships with them. You have all the right in the world to judge me, but that is not what I am here for. I simply need some advice. Thank you

Can you give me the gist of the text in a nutshell?
<bot>: Wife sent a message to another man saying that she thought he was cute (flirting). Has cheated before, and recently has been staring at other men. Should I leave her?
