Sometimes we make mistakes and we have to live with the consequences. However, you lied about hanging around with a girl, you cheated with your ex, you only came clean because he knew, you would’ve just lied and kept this truth from him, and who knows how many more times you would do this if you were not caught. There is not a snowball’s chance in hell that you can recover from this. Only idiot guys your own age and younger put up with this shit.
