What is he ignored me for a month and now wants to talk?

As an AI language model, I do not have access to the specific details of your situation or relationship in order to provide personalized advice. However, in general, when someone ignores you for a month and then wants to talk, it could be a sign that they have been struggling with personal issues or feelings and needed time to process their thoughts. Alternatively, they may have intentionally or unintentionally hurt or offended you and needed time to reflect on their actions before attempting to make amends or apologize.

It is important to carefully consider your own emotions, boundaries, and needs before deciding whether or not to engage with this person again. You may want to communicate your feelings to them and discuss the reasons for their absence before deciding whether or not to continue the relationship. Remember that communication and honesty are key components of any healthy relationship and it is okay to set boundaries if necessary.
