my boyfriend doesn’t understand me

Hi, I [20F] have been with my bf [22M] for about 7 months now. He is an amazing guy on paper, but I can’t get over how it doesn’t feel as though he understands who I really am. He knows my favorite color, he could tell you my favorite place to eat, but he doesn’t understand how to love me. He doesn’t compliment me anymore, he doesn’t get me flowers anymore, he doesn’t love me how he did when he first pursued me. I’ve brought it up so many times trying to tell him how I receive love and all he can say is that he feels as though he “can’t do anything right”. It hurts to hear that but also, I do feel like I’m asking for the bare minimum. I’ve tried to ask if there’s a bigger issue, but this is my fourth month begging and we are going long distance soon and it’s really worrying me. I don’t want compliments because I’m insecure, but it’s gotten to the point where he compliments me so little it affects me to where I over think heavily on this. I have communicated this all to him and he just doesn’t understand why I’m asking for any of this. Any advice on how to approach this, or maybe even ways I can do better? Am I going to tear my relationship apart by continuing to ask for these things? Will a LDR be maintainable if he can’t meet these needs for me?
