I Appreciate Honesty

I don't want to be even. I want to be equal. Yes, there's a difference. Even in this sense relates to revenge, schemes, games, dishonesty, vulgar behavior and actions. Equal implies respect, dignity, tenderness, harmony and empathy.

I value honesty and expect it to be reciprocated. You could have been an adult and actually told me straightforward that you slept with your ex once more, rather than pretend I was your enemy for my previous (unanimous) actions. Save your excuses. Save your unsolicited reasoning.

Since this isn't what you want, then leave.

Simple as that.
