Does it even matter anymore?

Tonight was just one of those nights. I 55M had an appointment after work and then ran to the store to grab a few things I needed to make dinner. Asked my wife 50F if we needed anything while I was there. She said no. I get home and start making dinner (chicken pot pie). While making dinner had to use a bag of frozen mix veggies which had green beans in it, not one of my favorites, so I picked out the green beans and made it without them. Wife is showering and watching TV as I cook. Dinner is ready and she goes to grab a drink and we are out if cranberry juice and of course it's my fault because I didn't get it at the store even though I asked if she needed anything and she said no. Then we are eating and she gets mad because I took the green beans out of the frozen veggies. That's just the point we are at. I know they are a symptom and not the actual problem but some days I just can't seem to do anything right in her eyes. Thanks for letting me vent.
