When a girl says she has a boyfriend, it's essential to respect her relationship status and boundaries. Here are some appropriate responses:
Respectful acknowledgment: "I appreciate you letting me know, and I respect your relationship."
Friendly response: "That's cool. I'm happy for you and your boyfriend."
Keep the conversation light: "No problem! So, did you see that new movie that came out?"
Change the topic: "Alright, moving on. Have you been to that new coffee shop in town?"
Maintain friendship: "I value our friendship regardless, and I'm glad we can still hang out as friends."
Avoid pushing further: "Got it. Let's just enjoy our time as friends then."
Politely exit the conversation: "Thanks for letting me know. I'll catch you later."
Remember, it's essential to be respectful and not pursue anything further romantically if she's in a committed relationship. If she ever becomes single in the future and shows interest, then you can consider exploring the possibility of a romantic relationship if you both feel the same way. However, for now, focus on maintaining a positive and respectful friendship.
