I feel he treats me less than

My husbands best friend is getting married in Hawaii New Year’s Day. My husband is the breadwinner at the moment and I am looking for work and help out in every single way I can. He makes a lot of money and wants to buy himself an expensive suit but doesn’t want me to buy anything. He said i Can wear what I have - I don’t have any dress for weddings given that I’ve never gone to one this formal and flashy. It makes me feel a bit bad that he won’t ever offer to buy me something and I never ask for anything from him. All I buy is groceries and stuff for our home since we just bought it. I am very good with money and used up all my hard earned saving to build a life with him. He likes to put in my face that he bought us the tickets and that’s our xmas gift (he bought it a year ago so very cheap) and that that’s all we will have and won’t celebrate Xmas. It just hurts a bit because I’m not hard to please and even a $50 gift would make me happy. He loves to spend money on other things that are useless anyways. I got a clear understanding that he only cares about himself when we usually make one another iced coffees. Yesterday he made it only for himself and said there’s not enough ice for me to have one so he just enjoyed his on his own. It’s just the little things I pick up on and it hurts my feelings. Im feeling emotional right now and feel like he always puts himself first rather than it being equal.
