Just wanted to chime in, you feeling sorry for him isn’t weakness!
It takes bravery and strength to hold space in your heart and mind to be open to trusting others (in general, not him specifically). You are very brave and strong for keeping your own ability to be compassionate.
However, the codependency lie that all strong, open-hearted people have to look out for is the lie that “having sympathy=actively doing work to give other people what they want.” That is just not true. Feeling compassion and sympathy does not require you to light yourself on fire to keep someone else warm.
So just wanted to say, I think you feeling these very human feelings of compassion are an indication of the strength and resilience of your emotional body. But if those thoughts make you feel guilty for not “doing more” I think that’s based on a false “if A, then B” assumption—“if I’m a good person and I feel sympathy for someone, then I need to caretake for them and make their life better or I’m suddenly a bad person.” Seriously, who taught us that nonsense???
