Further to your Query I called the office of Sayyid Sistani and they said:
You must convince your husband to give you the divorce. A representative of Agha can only give Talaq if the husband has been abusing his wife. E.g. not providing her with food, clothing, shelter, etc. Or physically abusing her.
In your case, since you are not living together, you must come to an understanding where he will be ready to leave you for a material return.
In this case your family should offer him a return of some amount of money or so to grant you your Talaq. (This is the actual meaning of khula).
On a side note, if he is your first hand cousin as in 'Rahim', he cannot ask back for the gifts he has given you especially the ones that have already been used off. E.g. food items, clothes that are perished etc.
I hope this was useful.
