I cancelled a date with a guy who lost his dad recently because he didn’t buy me flowers on the first date

I went on a date with a guy and he was very calm and didn’t talk much. I tried to initiate conversation but he seemed very reserved. I didn’t buy him anything during our date but he paid for my food and my drink. After our date ended he walked me home and gave me a kiss on the cheek. I didn’t hear from him for two days until he messaged me saying he wanted to take me out for dinner at an expensive restaurant. I agreed and said yes as I’m not fussy when it comes to going out on dates. He said “don’t worry I will come pick you up so you don’t need to walk”, I said okay and he said “I’m going to show you how a real man treats his lady”, I didn’t say anything. So he came to pick me up and I wore a red dress. As soon as he walked in he looked shocked and said “wow, you look beautiful” and I said thanks. He didn’t buy me flowers and I thought that was very rude. He took me to a restaurant and we ate seafood and desert and again he paid for everything. I was very annoyed at him the whole time because of the fact that he didn’t buy me flowers and didn’t even buy me a drink proving that he’s a cheapskate. I told him I needed to go to the bathroom to powder my nose and I went to the bathroom and texted my cousin. My cousin asked me how the date was going I said he’s being very rude and I don’t like him. My cousin said “how’s he being rude, he’s taking you out on dates every day”. I said “yeah but he didn’t buy me flowers today and didn’t buy me a drink, I don’t think he’s serious about a relationship”. My cousin said “he lost his dad recently so be patient with him and maybe he doesn’t have flowers in his mind right now”. I asked him how long ago did he lose his dad and he said 2 months ago, I said that’s a long time ago so he has no excuse for him not buying me a bouquet of flowers. My cousin said “yeah you’re right, if he doesn’t have flowers in his mind he’s definitely not the marrying type”. I came back out of the bathroom and told him I wasn’t feeling good and wanted to go home. He said okay and dropped me off home. When we were outside he said “I really like you and I want to take care of you and marry you”, I said “I don’t think that’s possible anymore” and he asked me why. I said “you didn’t even buy me flowers on our dates and you’re telling me you want to marry me? You’re not the type of guy I want to marry”. He got very sad and said “okay, I didn’t know you wanted flowers, I’ll buy you flowers next time” and I said “there won’t be a next time”. He looked so defeated and sad and walked away. Now I feel bad for standing a guy up and I really want to give him another chance but he’s not the perfect guy for me.
