Boyfriend problems !

Soo ive been with my boyfriend for 7 years and the relationship is great! Its just that i would LOVE for him to be a bit more romantic, its the main issue i have with him. I do my part by sending him love and appreciation notes on his lunchbag, dedicate songs to him, role play when being intimate lol i try to keep it intresting and show him how much i care, but yet he doesn't. I know he loves me but if he were to just show it , it would mean a lot to me. I tried talking to him, and letting him know how it makes me feel, he says he's going to try but doesn't, what should i try ?
