SMB,
You have taken the appropriate stance. You have done the hard part, stick with it....he sounds very much an addict. Expect manipulation, tears, anger, LOVE, all to get you to let your guard down and let him back in. Maybe, now, he will get his act together, or maybe he will keep on keeping on? All you can do is remove yourself from that situation. Hate to say this, but we have to be able to carry our own weight in this world and your BF can't even do that because he is too busy finding ways to drink. From my observation, it takes a pretty significant shift for people to get into recovery from addiction...he sounds a long way from that. Keep coming here and read within the forum. There is a depth to this disease that is not obvious and it akin to the image of the tip of the iceberg.
