She's clinging to you because she has nothing else going on in her life. she's not going to school or seeking to move up in life so she attaches herself to you so that you can do the hard work that she won't do for you. Best to let this one go and move on.

Walk away from her. If you get bored in a few months, then re-open the relationship and you'll be entertained for a while. Be aware, most people would consider this amoral.
If she calls, don't answer the phone. If you're on the social networks, drop her and/or stop using it. Be firm with cutting off communication. Make yourself very unavailable (home projects are wonderful) and busy.
