I am sorry for your difficult situation. It sounds like he is feeling worthless, and therefore assumes your feeling the same ways out him- naturally leading to the thought of you idolizing someone else above him. I know it is difficult to be calm and loving when you feel attacked, but think of what you love about him and what you admire, respect, appreciate that he does/ has done. Then tell him those things/feelings, and how they stand out above other people to you. This will make him feel valued despite being jobless and down, and will remind you of the good things he has brought to your life ( hopefully ). Ask him ( calmly ) to tell you what you have done in the past to lose his trust? Maybe this will remind him that he has no reason to distrust you. Most importantly, stay calm- don't entertain his ridiculous thoughts with an argument- this will only add weight to his unfounded suspicions and make you upset. I truly hope this works out in the best way possible for you.
