I agree.
I also hope this is helpful:
You can choose to see him (although this may take work) how you want: as a predator or as someone who was doing the best they could with what they had.
I have found that, ultimately, I find it easier on ME to choose to see people as doing the best they could with what they had.
That does not mean you have to classify his behavior from Wrong to Right. It does not mean that suddenly your feelings of anger, abandonment, despair, etc. are illegitimate. It does not mean that you have to have anything to do with him.
it's just a choice that gets you on the road to knowing that we are all always doing the best we can with what we have.
You never know what someone else has been through. And it might just be you do not understand his behavior because YOU are a bigger, and better, person who is more highly evolved in maturity and respect.
