Your H has a lot of the same concerns my H had as well. One of my H's main concerns with me, and also the main cause of our arguments, was to do with money. We are tight with money as well, and this caused a great deal of stress and pressure on my husband. He tried to talk to me about it in the past and I kind of blew him off or made excuses. This caused even more problems.
We ended up shutting each other out and not talking about anything and that made things much worse. We both started to feel a lot of resentment, but didn't express our feelings to each other. It's good that your H is being honest with what is bothering him about the money. This is a real and important issue to him. I would take this as a valid concern of his and have a talk about how you can move forward and fix things. You can come up with a plan together.
