What are some good ways to make it up to your girlfriend?

You’re right that flowers alone aren’t enough to truly make amends and repair the trust after forgetting such an important occasion. Rebuilding takes time and genuine effort.

Some heartfelt gestures to consider:

  • Write her a sincere letter expressing your regret, acknowledging how much she means to you, and committing to being a more attentive partner.
  • Plan a special “do-over” celebration tailored to her interests to show you put real thought into it.
  • Check in with her feelings regularly, listen closely, and validate her hurt.

Most importantly, focus on being consistently trustworthy, attentive and appreciative in your daily actions going forward. Remembering “little” things will show her she’s a priority. Trust is rebuilt through changed behavior over time. Keep putting in the effort to strengthen your relationship. Couples counseling could also provide helpful guidance as you work through this.
