I don't know how to confess what I did to my partner.
Why can't you confess to your partner?
I just can't bring myself to be honest with my love.
I know it can be difficult to confess to a partner when you did something wrong, but you should be honest with them. Not telling them what happened will just make it worse when they find out what you did. If you confess, you can work through the issue with them.
I know but I'm such an evil person.
I don't think you should put yourself down like that, everyone makes mistakes and it takes a lot of courage to own up to it all! Since they are your partner, you can be sure they would understand and be proud of you telling the truth.
