Well, my wife is clearly going through some growing pains. I don't blame her, adjusting to my new life approach will be difficult for her. I posted last week about how my wife exploded when I wouldn't say sorry, and here I am again with yet another outburst resulting from basically nothing.

My MIL babysits our 4-month-old every Tuesday. She's really wonderful, does it with a smile on her face (she loves being with her granddaughter). She also frequently brings us groceries and has dinner waiting for me when I get home from work. I don't necessarily like the fact that she brings us groceries, as I don't like to appear dependent on my in-laws, but that's for another time.

Yesterday, I get home from what was the best day of work I've had in a long while. I got a glowing end of the year review, they threw in a nice unexpected bonus (money around the company has been tight lately), and they even invited me to a black tie event this evening that someone at my level is not usually invited to. I told my wife about it during the day.

More background: I rarely see my daughter during the week, since I leave before she wakes up and come home after she's already asleep. Yesterday I came home from work a little early so I could spend some time with her. My MIL starts to pack up when my wife walks in. I'm playing with my baby at this point, and my MIL is gathering her things together to carry with her to her car, which was a few blocks away. My wife tells her she'll bring down a few bags and wait for her in the lobby of our building until she pulls the car around. MIL leaves, wife turns to me while I'm playing with baby, "Pretty great news about the bonus." "What can I say? I'm a baller." "Well, baller, will you bring down those bags for my mom?" "No, I'm playing with Daughter before she goes to sleep."
Now, in the past, if my wife asked me for anything, I would drop everything to do it. Classic beta. This was a change to the power structure, and it scared her. Understandable.

"What do you mean you won't bring down the bags?"
"You told your mom you'd bring them down. I'm playing with Daughter, who I haven't seen all day (shouldn't have explained myself). You can bring them down."
"You're really not going to help."
"I'm playing with Daughter. You can take them down as you agreed to." "I can't believe you. My mom asks for one little thing (she didn't ask, Wife did.), and you can't do it? After all that she does for us?" (Exactly the reason I don't like when my in-laws do things for me) "Wife, if you continue speaking to me like this, you'll never get your way."
"Fine." Storms out of apartment to bring bags downstairs, something that took her all of 5 minutes.

Comes back up, while I'm changing our daughter, who has since created quite an explosion all over her clothes. "I can't believe the level of disrespect you just showed my mother. You would never act like that if it was your mom (I let out a slight chuckle). You would have run downstairs to help her without her even asking." I have a ridiculous grin on my face for my daughter to keep her laughing while I'm changing her. I don't change my expression or demeanor at all. She continues spouting nonsense at a high audible level while my daughter is on the changing table and I'm trying to keep her calm.

"If you continue to speak to me like this, I have no reason to interact with you. I have better and more productive things to do." Deadpan, firm.

"I just can't believe you would treat my mom like that. You don't think of anyone but yourself. You should've volunteered to help her. I'm so hurt right now. Frankly, you should be embarrassed about how you just acted."

At this, I can't help myself, and I let out a pretty hearty chuckle. Nothing too loud, just a, "heh heh." She then leaves the room, I finish changing our daughter and come out of Daughter's room. She tries to grab our daughter out of my hands. "Excuse me?"

"I'm ready to feed her to put her to bed."

"That's not how you ask."

She says, "can you please give me our daughter so that I can feed her and put her to bed?" Before I have a chance to respond, she again grabs for our baby. At this point if I don't relent, it will turn into a safety hazard, so I give her our daughter. I hate, HATE that she got our daughter involved in this, and that she would put Daughter's safety in jeopardy just because of this. I'm so furious at this point I know that if I say or do anything else, it will definitely break frame and I'll turn into the bad guy. As she starts feeding our daughter, I quietly and calmly put on my sweatshirt, grab my book, and head out the door. I then spend the next three hours out of the apartment with my phone off, reading at a coffee shop. When I get home, she's sleeping. I go about my business, get into bed, wake up before the crack of dawn, and head to the gym, then to work. We haven't said a word to each other since.

As always, feedback is greatly appreciated. Again, I'm still very new to this.
