I was dating a guy 8 years ago.One day a common friend told me that he graduated from graduate school.So, I wrote him an email to his job account saying congratulations for your graduation, what do you plan to do now. It took him a week to reply and he said what a nice surprise to see your email, sorry for taking so long to reply, tell me about your life now, where are you. I replied, and it has been some days and still donŽt get a reply. Do you think he is not interested, and replying only for courtesy? what could I ask him to know about his dating status now in a subtle way?
