I see codependence on a continuum. Some of us are more so than others based upon lots of factors. Then you add on other things like abuse, being a child of an alcoholic, etc and you are at a different place on the continuum.
I try not to get hung up on what something is defined as. More so that I see it in myself and try to address is in healthier ways. I have a pretty high tolerance for some things and other things are a deal breaker for me.
If he abused you and you tossed him out and you were negotiating taking him back, that would ring codependent alarm bells in me. On the other side of it, if it were sub zero temperatures and he were a block of ice on the doorstep, handing him a blanket wouldn't be codependent to me.
I have no experience with alcholism until now and I already see that my boundaries get eroded easily. If I don't work on that, I could easily see lots of codependency in me emerging. It is an individual assessment I think.
