AITK for reacting angrily to my girlfriend?

Too long story. Posting this from my new account because I am hesitant to post this from my main.

So I (22M) am in a relationship with(22F). It's been 2 years almost. My gf has an habit of ordering me to do stuff, like "buy me this , buy me that", "bring me this, bring me that", even when we both are eating she would ask me to serve the food or bring the food at the table from the counter.

I am leaving aside paying because haven't even seen her put out the wallet from her purse ever(except only when she needed something small for herself).

She would give all her luggage on my back even when I am occupied with my own luggage. Always tries to order the most expensive food at the restaurant because she knows that she won't have to pay for it. She would often make jokes on me but when I do it back, she gets angry and tells me to not talk to her that way.

I got her lot of gifts in her birthdays, or whenever she told me she needed something. But not a single time my efforts were reciprocated. When she used to feel low I stayed with her, gave her emotional support but when I needed it, she ignored it as if she didn't even know me.

Even during special occasions like some festivals(I am from Bengal so there are many festivals time to time), she would ask me "you haven't bought me anything?" as if I was her father who should buy her items from time to time. So basically her efforts in this relationship is zero. Pure zero. Financial, emotional, etc.

So one day I lashed out at her , because I got really frustrated, angry and said "Why can't you do it yourself, am I your servant? Why always I have to do everything?"

Listening to that, she smiled and then said "what do you even do?" . I was shocked to hear that. When I am the one pulling all the weight, she asked "what do you even do?" to me. She has used this phrase very often in our relationship.

Feeling mentally blocked and disrupted rn.

Am I the Kameena(AITK) for reacting angrily to her ?
