I need relationship help. What should I do?

I texted this guy so much and we were really close. He asked me out a lot but I said I wasn’t ready for a relationship. He seemed fine with it and said he would wait but kept pressuring me and taking up all my time. Eventually, I had enough and told him I needed a break. Now he’s really depressed and said he wants to die. What do I do!? Am I even over him?? What should I think and feel?
