First, happy birthday. Second, I think you redeemed yourself and didn’t let it go too far.
I’m sorry, but she is a real selfish biotch to be sleeping with another man and come into your bedroom in her underwear and hug you and tease you when she sleeping with another man. That is so low life, classless and disrespectful. Go back to that and you won’t want to invite her anywhere.
You did t let anyone down and you aren’t a moron. You are human.
