Just to clarify Jack, I like to talk from responsibility as a perspective of what we can control. When two responsible people join their lives, a great, long term and potential intimate relationship can be formed.
By all means, your GF could have come from a "more responsible" position. Outside of any psych analysis, she was "less than supportive and responsible" in the relationship.
She too would do well to take a look at herself and discover how else that shows up in her life and how she can become an even greater person...
In the mean time, it still remains you being responsible for you...
