I don't see "enabling" the same way you do, Susan, but if it helps you and your brother, then I'm all for it.

To me, enabling is to allow another person to keep acting and/or thinking the wrong way, to allow them to stay stuck in a place that would benefit them to move out of.

IMO, there's nothing wrong with supporting someone through a bad spot when all they really need is some consideration, acceptance and love. There ARE some things that people can't physically or mentally overcome. That's when they need what you give your brother. Absolutely nothing wrong with that! That's what family is supposed to be about.
