Dear rry, you say that you don't have the heart to "kick him out YET". This begs the question of what will give you the "Heart"? Hammer recently talked about the concept of co-dependent types (like us) tend to operate from a "Rules" mentality. (Alcoholics from a Feeling-based position). For example: "I can't leave him until he hits me".
I wonder if this might apply to you in your situation. Is there a rule or certain thing that will be your line i n the sand?
It is also said that when one won't/can't leave a toxic situation--the reason lies somewhere in the FOG---F=fear O=obligation G=guilt. I tend to believe this, empirically.
These are some of my thoughts about your post....
