He is a big boy an made choices in his life sparkles. Let him live with his decisions. It is not your job to look after him. You were fired from that job. I know it's hard not to stay involved. This could be an opportunity for him to see things you did for him.
It is difficult to stay away when the heart yearns for someone. The best thing to do is give yourself even 10 minutes to think through the positives and negatives of your actions. Give it longer if it is a big deal and make a decision with your head after you have really thought it through.
The person that you will spend the most time with in your life is yourself, so make yourself as interesting as possible.
