Am I wrong for thinking my boyfriend is doing too much?

I haven't told him this but he has in the past financed a car for his parents. He mentioned recently that he wanted to get a car but he was going to wait until later in the year to sort that out. Mostly as we are going on holiday and planning for another trip uk based. Anyways his sister passed her driving test this week and she's been saying she wants to buy a car. Initially he was saying to her that she needs to consider all the costs and discussed it with his mum so they were on the same page. Anyways he told me on Friday that she planned last minute to go on holiday and he suggested she hold back on paying rent if it was a stretch until she returned. She said she'll think about it and get back to him in 48hrs. He then went on to say that he's decided that he will just buy the car for his sister instead.
She is 23 he is 34.

He is well paid and owns his own property not our right... But has a mortgage.
My issue is that he seems to do this a lot, as if he is the parent in his family and it's concerning to me that he doesn't see why I have an issue with it.
I was raised to have ambition and always try to do for myself first and if I need help ask. So I am fiercely independent. Something that he also struggles with. I may not be as successful as he is but I don't reach my hand out at every moment. I also find it insulting that in the past I have mentioned I didn't ask him to pay for my holiday and he snapped at me claiming he couldn't afford to pay for me when a few days prior he mentioned his sister asking him for money.
He seems to take his gripes out on me when they are unjust. Boundaries is a massive issue in his house for example he bakes, he'll do a batch for the house and decided to do some for me which he set aside, when he got to mine he said he didn't have them as they ate theirs and then dipped into my batch. He didn't see anything wrong with it but instead said he would just bake more. He didn't understand why I was so angry. Because it's only food!
