I'm probably BU and it's definitely a storm in a teacup, so I suspect I'm going to get my arse handed to me.
DS11 woke me up this morning moaning because DH told him he wasn't allowed to watch the Simpsons today. DS11 spent most of yesterday watching the Simpsons (we had a chill out day), but DH had told him this was ok as it was the holidays, so seemed like an about turn this morning. From my perspective I was annoyed as DH isn't going to be at home this afternoon so effectively I will have to enforce an instruction I didn't agree to and don't particularly agree with.
Anyway, I went downstairs to have a chat with DH, so asked to come and to talk to me away from MIL (we're a support bubble). It didn't go very well, I didn't explain myself very well, I didn't shout but I definitely expressed my annoyance. DH shouted a little and stormed off as MIL came in. I said "oh dear that didn't go well" and made MIL some breakfast.
I went off to find DH and apologise. He said he was too angry to talk, so I left him alone.
DH is now downstairs building lego with DS (well DS is watching) and MIL is in the same room. DH hasn't spoken to me since but is amicably talking to DS and MIL. Because DH hasn't spoken to me I feel miserable and also a bit left out. Clearly I could just sit at the table with everyone else and brazen it out. I just feel a bit uncomfortable in my own home.
YABU - just crack on with your day and brazen it out, no need to feel uncomfortable
YANBU - Carry on feeling uncomfortable and doing something in a different room
