Have you ever cheated on your gf and then exposed everything?
What was the aftermath? How did you move on?
I'm still trying to recover from my particular fuck fest. I should have never come as "clean" as I did. I can't even listen to a lot of music I like when I'm around her (which is often) because it "triggers" memories.
I wish I had kept lying.
Guys?
Hold on...
You cheated on her, she took you back, and YOU'RE the one getting upset?
Feels like bait.
Break up with her.
It may sound harsh, but nothing good will come out of a relationship with zero trust and happiness. You wanting to lie to her is already a major red flag.
