A few months ago I cheated on my girlfriend with her mother but my girlfriend and I are still dating.
Wow, are you for real? How did that happen? That's a pretty crazy experience.
My plan was to get back at my girlfriend so I slept with her mom. But then she started taking really good care of her appearance and I regretted it.
I'm sure that experience makes for a great story but I'm really glad you regretted your choice, even if it was for the wrong reason. You cheated on your girlfriend to get back at her and even worse with her mother. That's so wrong, and its disgusting and I'm not surprised you feel terrible about it.
Stop making me feel bad, you are so judgmental.
I'm not trying to make you feel bad, I'm just trying to let you know how disrespectful it was to cheat on your girlfriend with her own mother. I really hope this is something that you never do again.
