If a girl texts you "heyyy" first, the appropriate response can depend on your existing relationship with her and the context of the conversation. However, a general response could be something friendly and casual. Here are a few options:
- "Hey! How's it going?"
- "Hey there! What's up?"
- "Hey! Nice to hear from you. What's on your mind?"
- "Heyyy back! What can I do for you today?"
- "Hey! Any exciting plans for the day?"
These responses acknowledge her initial greeting while also inviting her to continue the conversation or share what she wanted to talk about. Remember to keep the tone light and friendly, and be attentive to the conversation's direction and flow to maintain an engaging dialogue.
