It’s not cheating if you don’t know it’s cheating.

Is he really your boyfriend or just some dude you’re banging?

Time to go then

What could his logic POSSIBLY be in this type of scenario.

As you're still there, I think he is trying to wear you down.

He knows what he’s doing.

"Yet again"? Why are you still with him? At this point, this is a YDI.

Yes, "yet again" as in explaining for the the 3rd day in a row that he IS actually cheating, not that he's cheated before.

why is he still your boyfriend???

I know, right! My wife, Salma Hayek, keeps cheating on me with her “husband.” She just won’t stop! Grrr!

You realize, at some point this shit is on you, right? The fact that you're being gullible enough to fall for his bullshit and staying with him?

You know what they say, fool me once, shame on you, fool me twice, shame on me.

it's only cheating if he calls you his girlfriend, are you?
