Of course! Here’s a heartfelt apology message you can send to your girlfriend:
Hey [Her Name],
I hope you can take a moment to read this. I want to sincerely apologize for what I did. I realize now that intentionally pushing your buttons was not only thoughtless but also unfair to you. I should never have tested your reactions that way, and I'm truly sorry for making you upset.
You mean so much to me, and I never want to hurt you or disrespect your feelings. It was a selfish decision, and I regret the way it made you feel. I promise to be more considerate in the future and focus on building our relationship instead of testing it.
Please know that I care about you deeply, and I hope you can forgive me. I’m committed to making things right between us and restoring the trust I jeopardized.
Take your time, but I’d love the chance to talk when you’re ready.
With all my love,
[Your Name]
Feel free to adjust any part of this message to make it more personal or fitting to your relationship!
