Should I meet him?

Emily
I broke up with my bf a month ago and now he won't leave me alone. We dated for a year and a half. A few months ago I broke up with him and he tried to kill himself and was sent to a psychiatric center. He begged me to get back with him and I did. Ever since that, he threatened to kill himself if I ever left him. Now a month into the breakup he still won't leave me alone. He is 18 and going into the Air Force and leaving for basic training. He asked me to see him before he leaves. Is that a good idea?
