BIL came to us for Christmas. DH had spent weeks prepping an extravagant meal despite our DD only being six months old. BIL argued with DH about the food, refused to help with the washing up, and said he'd have preferred to have got pizza in. I ended up feeding DD in the bedroom at this point because I didn't want her to listen to it (she was about 6 mo)
BIL suggested we go for a meal "to clear the air" a few weeks later. We did so, everything seemed fine. I haven't seen him since.
Then he contacts DH randomly yesterday to say that he's still angry about Christmas?!? And that I made him feel awkward because I was breastfeeding when he arrived. I've felt stressed ever since because I'm being scapegoated but didn't do anything wrong. AIBU to be this affected by being blamed when I hadn't done anything? If so, how do I get rid of the stress?
