Red flag that he doesn’t put effort in when dating?

Been friends for 5 years and started dating a month ago. I don’t hear from him until around midday. No morning or night messages unless he’s feeling cheeky in the evening.
The last girl he was into, he drove to get her coffee and got her flowers and did all this stuff. I love flowers so much but haven’t gotten any… at this point I’m like I don’t care about the flowers, just text me in the morning and night too. A simple good morning or goodnight, doesn’t have to be full conversation.
This was our conversation and he’s just not getting it… I don’t know what to do because it’ll be so hard to throw our 5 years of friendship away.

His response the the last message was “because you keep bringing it up. I’m literally more than happy to wait a year for you to come back”
