Caretaker,
First and foremost, no conditions means just that. To take the behavior presented by others so personally is counterproductive and frankly, unhealthy. You have no idea what thought processes were used by your nephew to make the decisions he made regarding
his Vibe, and in reality, it absolutely does not matter.
I think it's normal for people to consider how they would handle a situation and then question the thinking of others when the behaviors don't mesh. Such is life. I hope someday you will realize the true joy in helping someone "without conditions." That old saying, "it's better to give than receive" is so true.
I hope you can stop letting the actions of others cast a negative shadow over your health and well being. Stress is a killer and getting upset over the fact that your nephew sold his Vibe to get another car is stress you certainly do not need.
I realize this reply is rather preachy and non-therapeutic. I am not a therapist. I'm just a good old boy who through life experience and maturity has realized that life is way too short to let petty non-issues cause undo stress and heartache. Someone once told me, "Don't sweat the petty things and don't pet the sweaty things."
Take a deep breath and think about how you helped someone who needed help at the time. You and your wife did a good thing. Be proud of that.
