Anger in building up in me!!!

I cant believe when my bro questioned me why these things were bought without his acknowledgement. But in the first place did he put his heart in looking after what the family's need? First is the ions cleaner, then the air-cooler. Lucky I told him about the air-cooler before we bought it. Then my dad said he don't like it. We wanted to make him feel comfortable and ended up, we become the one who were blamed. And he said that it was a mistake and he didn't agree to it. So angry with my dad. Should not have spare our thoughts for him to make him feel more comfortable. In the end, blamed by him, then later by my bro saying that he wont pay for the things. Stupid... don't understand them. Me, my sis and my mum should have just pulled ourselves away, far away from all these things. But we just can't. Had been scolded so many times by my dad and yet we are still running errors for him. I really don't wish to have him say thank you to us but please appreciate the things we have done for you. And bro, please take note that it is not that I dont want to talk to you. Is just that every time I talk to you, I see your "angry face" or "why keep me busy face" that really put me off. Also please dont say we didn't tell you these things. Sometimes, things were bought at the very urgent moment and need to be done quick. To be frank, I never think ahead and I am not sure about you. But I believe sis has thought way ahead of me and plan the pave for our benefits. She is calculative not because she wants money. Is just that she cant feel appreciated for the efforts she has done. Please my family give each other some breathing space and stop biting each other. I hated to be in this family too. But can I run from it? I don't think so.
