It's been a year since I broke up with my ex-boyfriend He texted me and asked me how I was. Should I ignore him?

If you have a stable life, leave him alone. The previous person sent you a message to test your current situation. If you don't reply, he will judge that you are taken. If you reply, he will feel that he still has a chance. Don't take this step when you have a stable life and still think about him!
