The conversation between human and AI assistant.
Why do guys take forever to text back, or they don't text back at all?
That makes sense. What about if I've already texted him and he still hasn't responded?
If it's been a while and you're still waiting for a response, you could try sending a follow-up message. Keep it light and friendly, and perhaps add a question or suggestion that might encourage him to respond. But be prepared to accept that he may not be interested or may not have the time or capacity to respond as quickly as you'd like.
