Welcome to SR KMJ!
Since you've mentioned his verbal abuse, and your concern for the possibility of his increasing anger if you stop enabling, I'd like to suggest that you read the stickies at the top of the forum. In particular, click on 'About Abuse'. In there are several links, two of which I recommend you take a look at....'the one on verbal abuse', and the other which is 'DV and chemically involved partners'.
I'm not saying whether these apply to you or not, but, it might be something that could be helpful to you when considering your particular situation. The second one in particular speaks to stopping enabling/detaching and the potential risks that are involved 'if' the person with you is at all of a violent nature. Again, just something to be aware of. Only 'you' know the severity and particulars of your situation.
Keep coming back.
