Ex's phone has been off for days. Should I go and see if he's alive?

Ex's phone has been off for days. I'm stupid for worrying but I am. I just wanna make sure he's alive. Maybe he changed his number and he really doesn't want me anymore. Either way It would still help for me to get over him. The only day I have off is Sunday, and by then it will be a full week that his phone is off. Bad idea? Please honest thoughts.
