It sounds as if this situation is draining for your energy. While your significant other is going through hard times, he might not be aware of how it is affecting you. It would not solve all your problems, of course, but perhaps if he was made to understand your perspective, he would help you through certains tasks. Perhaps some relatives would be willing to help you? It is good that he’s trying to find work.
Please take care of yourself. Do what it takes for you to be okay.
