ANSWER:
This is something between you and Allah!
If you repented from your sins, you can’t regret it and feel remorseful for breaking it! Allah will not forgive you if you are not remorseful over such sins and repenting sincerely to Him.
A sign of true repentance is that you move on with your life, being remorseful and ashamed from what you had done and never think positively of your partner in crime as this would mean that your repentance is not genuine or real.
