Need support navigating the change in my marriage

[G8r]

Got stuck in traffic today and couldn't pick up D3 from day care like I told WW so I had to call her and ask her to get D3. She was pleasant enough on the phone but, my goodness, was she spewing when she got home. The more I ignored her, the angrier she got. At one point I left room and told her that she wouldn't talk to me the way she was. She countered my repeating my line to me which I ignored. She then decided that she was going to rake D3 with her to trivia so I came back into the room and told her to get. That didn't go over well with her. She was standing there with her hands on her hips saying excuse me? I only told her to get because she was leaving anyway and she was in full on rage mode in front of D3. My ignoring her after that and trying to escort D3 into another room didn't fly with her so she followed. Grrrr... D3 went to bathroom and she continental to spew. I eventually whispered to her, zip it. Stop arguing in front of D3. She had audacity to tell me it was my fault because I didn't trattoria her right like it had never treated her right. Aye, aye, aye. Oh well. Let's See what the rest of the night holds.
