<human>: Can you condense the text into three sentences or less?

I'll keep this short and sweet: basically my 25-year-old boyfriend of 7 months shared with me that he almost cheated on his last ex-girlfriend of 3 years. He said he was on facebook, telling this girl to come over to his house so he could fuck her, when his girlfriend walked by behind him and saw what he'd written. He said she got upset (obviously) and demaned to see the rest of his messages with this other girl. She then went on to confront the girl via facebook.

After telling me this story, he made no indication that he was sorry any of it had happened but that he was upset his ex had looked through the rest of his messages and spoken with the other girl.

I know the infidelity stories here get fairly intense and this is nothing really (is it?), but I'm starting to feel uncomfortable in the relationship. He's also mentioned how after a year or two he takes his girlfriends for granted. Is he throwing me small red flags that I should grab onto or am I being silly?
<bot>: Boyfriend almost cheated on his ex-girlfriend and afraid the same temptation will happen in our relationship. I feel weird.
