is it my fault?

i lost my husband last month from a car accident. the entire reason he was on the road was because of me. i was baking a batch a of brownies and ran out of coco powder so i asked my husband if he could go get some more. he had just gotten home from a long day of work and, despite being exhausted, immediately hopped up, grabbed his keys, and gave me a kiss goodbye. he got in the crash 12 minutes later because of me. because of fucking brownies.
