Guys I'm so angry right now

So pls tell me who is wrong here im so angry I need to hear it from other people….
My partner I have been with over 5 years is always asking me in front of people to pay for the things he wants…I think this is rude I would never do this I work over 40 hrs a week he diesnt work he’s 50 yrs old I’d be embarrassed to ask someone to pay for something for me but he seems to like doing it when I’ve told him I’m dont like it..we will go somewhere and he will see something he likes and take it to the counter then say are you going to buy this for me.i feel so awkward that I do buy for him but this weekend I refused to buy for him I told him how I feel and he said im wrong and he cancelled our night out that i booked a table for because he said he never heard from me obviously because I was angry how he been acting the day before ..not just cancelled but didn’t spk to me at all and he insulted me im so angry it isn’t the first time he acted this way ive had enough
