It has been over a month?

since my man of 8 yrs left me for being jealous and controlling.Our relationship was intense he still returns my calls saying he will meet me but never does.I know he is being influenced with his family.he still lives at home, and dumped me the minute his siter (who detests me) moved beside him.he spends every night at her place.I still call him every few minutes...should i leave him alone???
