Relationships

As a girlfriend, is it my obligation to buy him a wireless keyboard, curtain for his house, plate for stove, table lamp, pants for working?

My boyfriend just asked me to get wireless keyboard for laptop for his project but I disagree with it. He always asked me to buy things but this time i rejected it because i found him cheating on me. But he denied it. 2 days ago he asked me if i already buy the keyboard i said no. He immediately yelled at me and tell me “FUCKING STINGY” dont talk to me and chat with me. And he ended the call and blocked me. Wholeday he blocked me yesterday then unblocked me lastnight when he want to talk to me. Then this morning (Thursday) i thought everything is going well already so i greeted good morning and wished him a great day. But after he read my message at 7:51am he ignored and didn't reply me then he blocked me😔 . Then at around 9:52am he unblocked me and message me to get the keyboard but i didn't reply then he went to blocked me again till now. We usually talked after his lunch everyday but now its been 2 days that he doesn't call me at lunch time or chat me. Its always me who understand him and say sorry for my mistakes. I feel so tired understanding him. Were not staying together, I lived very far 1 and 1/2 hour by train. Whenever i explain or want to clarify something he will end the call or blocked me. Im 43 and he is 51. I feel worthless , Every Friday i bring veg to his house , now i feel like i want to stop buying. My effort is not valued. And Im the only one making effort communicating. Is he using me only? I feel so hurt🥲 He also scold me for buying things for my family. He want me to buy only for him. Do i need to blocked him too and ignore like he do to me?
