What can a person do about an ex(not in a marriage)who just won't get the message and get on with his life?

He must be about fifty, very possessive, unemployed for an extremely long time, basically living off his father’s pension and not making much of an effort to do much. The woman who had a relationship with this man, got tired of constantly “lending” money and being the one required to pull her weight constantly. Extreme jealousy issues(on his side) and generally things were not moving on. Now a year later he still approaches her, popping up suddenly almost wherever she is, begging for them to get back together! How does a person deal with such a case? He is not moving on or getting the message and not letting her move on either!
