Goldfish,
Quit for you and quit now is my advice. The fact that you are in love with someone who is familiar with the disease, understands it and is willing to support you is a great gift!
However with this great gift comes great responsibility, you must be honest with yourself, you must admit your powerlessness over alcohol and you must quit for YOU... not your boyfriend. If in your mind you are quitting for your boyfriend, I fear you may run the risk of resenting him and your relationship will end eventually anyways.
If you take that first step, for you, honestly, you will have a chance. I would recommend getting to A.A. and getting a sponsor as well as continuing to post here, the support is incredible.
Good luck, I hope this helps you.
John
