I'm going to ignore my girlfriend's compromise
Why would you ignore her compromise?
It feels like she's putting her bullshit before forgiveness. I shouldn't have to earn her forgiveness, man.
Being hurt by a partner can cause issues of distrust. If they don't feel like they can trust you any longer, they may end up wanting out of the relationship.
I never should have let her leave in the first place.
I'm sorry you're at a rocky point at your relationship, and I know it's tough to try and get out of it! But compromise is one of the most powerful tools in a relationship, so how about talking it out and making a deal with her?
