Very good post Huddy. I do think we hold on too tight and merely experiment with what we think we should be doing.
Then, when certain boundaries of ours are crossed I think we have our own wake-up moment where we figure out we really do need to focus on ourselves. Something snaps, things are never the same again and that rope is dropped too low to be bothered with again.
Keep going. But be aware of the tricks she will try.
