What is should i text him after a month of not talking?

As an AI language model, I don't have the context of your relationship with him. But, it's understandable to feel nervous or unsure about texting someone after not speaking for a significant period. If you feel comfortable reaching out, there's no harm in sending a message to spark a conversation. However, it's important to consider why you haven't spoken in a month and whether rekindling communication is in both of your best interests. It's always good to be honest, genuine, and respectful when you reach out.
