I've been going out with this guy for about 9 months and I decided not to see him again on Jan. but he kept emailing and calling me everyday (yes, from Jan to April) He waited for me near my house for a few days and just now I got an email and he said he is still waiting for me to come back to him. what should I do? The reason I don't want to see him anymore is because he asked me to marry him but I don't want to.
