<human>: Provide a brief overview of the text.

Warning, this is kind of long/convoluted but I would REALLY appreciate any and all input!!!

So, I am taking this Thursday, Friday and Monday off for my cousin's wedding 2 states away. Inventory at work is on Tuesday with a ton of prep work up until that point so me leaving is quite a pain to everyone else. I technically will be home Sunday night but wanted Monday off to recuperate. The thing is, my work is closed Friday and my boyfriend and I would like to leave on a trip Thursday after work. Traffic may be horrendous and mess everything up, so I want to offer to come in Monday if she will let me leave early on Thursday the 2nd. I will write what I am thinking of saying, please tell me if you think it is reasonable or absolutely ridiculous and something I should not even consider asking. Keep in mind that my boss is semi unpredictable, sometimes shes super chill other times totally insane.

"So I was feeling really guilty about leaving everyone high and dry for inventory prep. I was wanting Monday to recuperate from traveling, however I may be willing to come in instead. In lieu of that, my boyfriend and my anniversary is Friday and we are leaving for a trip on Thursday. I was wondering if I could leave at 1 to beat the traffic."

Is there a better way to word this? Am I being assuming or spoiled when I have already been given time off? I have worked their 2 years and 4 months, been promoted and am overall doing well in my position.
<bot>: I am already taking time off which is inconvenient for my coworkers, I want to know if switching it is completely unreasonable or even worth asking when it is less than a week apart.
