Let's do a little roleplay here. Let's say you get a little tipsy and were drinking. Do you think now that you could just forget your boyfriend and go have sex with two other people at the same time? And then just act as though it's no big deal? If you don't think you'd be "ok" with doing that to your boyfriend, then what right does he have that to do with you?

Don't except this. You accepted it too quickly, too easily. He'll do it again. Sure right now he's satisfied cause he was with these two other women. What happens a month down the road when he's only been with you and starts noticing all the OTHER pretty girls walking down the street? He's gonna do the same thing. And come back to you with the same lines, "It won't happen again. I got it out of my system. Please forgive me. I love you."

What a loser. Leave 'em.
