It sounds like either 1) he's grumpy because of outside influences or 2) he's grumpy because of you.
Instead of you "talking about how you feel" (which usually women convey in a complaining way, which just adds stress) I would ask what's bothering him and why he's stressed out. Tell him you're sorry if you've caused it and, if he doesn't respond, leave it at that and tell him your open to listening when he's ready to talk. Then, wait. Could take a couple of days. In the meantime, don't talk about any problems or issues, if you can help it.
