Need Advice!!!

My W just emailed me for the 2nd time in 60 days. It is nothing special just requesting that I leave all accumulated mail in the mailbox. But she at least said Hi and Thank you,. I plan not to respond tonight, but respond in the AM with a short reponse. W mail is in the mailbox. It seems like each time that I let her go and go dark that I get a response. Am I on the right path?
