Here are some cute girlfriend quotes I found:
- "You are in my heart and in my mind all day long."
- "If I know what love is, it is because of you."
- "My girlfriend has the prettiest face but she also have the biggest heart and I love her for that."
- "I love you right up to the moon—and back."
- "I’ve never had a moment’s doubt. I love you."
- "I can’t stop thinking about you."
- "You'll always be my girl."
I hope these quotes help you express your feelings to your girlfriend. Let me know if there's anything else I can help you with.
