Yes I agree, if it's a conscious 'choice' to be helpful without it taking it's toll on our well-being then I agree it's a healthy option. However, if the relationship starts to erode our sense of well being, then that's another matter. I personally have done both. As I have gotten older, I have decided my time on this earth is precious and I am more inclined to ask people to 'seek support for themselves' rather than 'be a primary source' of support. We live and learn, there is no wrong and right, we do what we can, and when we can't that's ok too :D
