<human>: I received a disturbing text at 2:30 am from my girlfriend [F/19] who lives 3000 miles away.
  Back story. We're both freshman in college living across the country from each other but we met in the 6th grade and have been together off and on since then. We know we have something special.
Her text was "I fucked up" which got me thinking the obvious. She cheated. Due to the time zone. By the time I saw it she was asleep so I had to wait until she woke up and then she told me. She told me she was sorry and it was a mistake while she was under the influence of pot and alcohol. I forgave her and told her it was okay. I told her I wasn't mad, just really hurt. 
    Why? Because early in the summer of 2015 I cheated on her twice with the same person and hid it from her for months. I also made the choice to cheat on her while 100% sober. I feel like I can't get mad at her for doing something under the influence I did sober.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: She cheated, but I cheated first. But she told me and I forgave her and am trying to make it work.
