I made a mistake and cheated on my girlfriend. Afterwards, I broke up with her and tried to make what I did sound rational.
Was there a reason why you cheated on her in the first place?
Because I didn't want to make things complicated and because I love her
If you loved her so much, you would not have cheated on her. It is wrong to cheat on your significant other, you should have left her before it got to that point.
What? I love her.
Cheating on your partner is a bad way to show them that you love them. All cheating is going to do is end your relationship, which means you are not going to be able to be with the one you love. Knowing the consequences of cheating may be a great motivator to avoid doing it.
