<human>: Throwaway account

So my wife's birthday was earlier this week.  Prior to this we had made plans to do something nice this coming Saturday (tomorrow) when my parents could watch our 12 month old.

The night of her birthday we get home and she's expecting me to take her somewhere.  I pointed out that we had planned to do something on Saturday (even canceled other plans with friends) but she had expressed the opinion that we should do something on both nights, going so far as to have requested the night off.  I knew she had asked for Saturday off in order to do something but I wasn't expecting (nor was it communicated) to have to do something that night.

At this point we had a low-level, passive-aggressive (no yelling) argument and I finally relented and agreed to take her somewhere.  I was moody and quiet for the rest of the evening and was quite frankly disappointed with the whole thing since I had bought her a nice gift and was looking forward to giving it to her as well as doing something nice on Saturday.

I won't lie, one of the big issues for me was the added expense.  I am currently the primary breadwinner so most of the financial planning (and responsibility) for our family falls on me.  We are expecting $3000-$4000 worth of medical (dental) expenses in the next two months as well as the extra expenses that come with the holidays and on top of that we're in the process of buying a house.  I should also mention that this sort of thing has happened before, where we make plans to go do something and she starts adding things on to the point where suddenly I'm spending two hundred dollars over the course of 4 hours.

I think the biggest frustration however, was I had actually gone out and bought something really nice (read: I didn't cheap out) that I knew she would like, had something nice planned and it felt like she was almost saying "what else have you got?" (it killed the gift-giving moment).

So what of it r/relationships, am I justified in my frustration or did I overreact?

Feel free to ask follow-up questions.

Give me the gist of the text in a nutshell
<bot>: Wife's birthday just came and went and she wanted to do more that was already planned and agreed upon, am I wrong for being frustrated and disappointed?
