Attention please

I feel like I'm putting more effort into my relationship. I feel like I'm being needy and he just is effortless, I guess. In the beginning of our relationship he was head over heels and was always romantic and put his arm around me but now it's been almost a year and he's stopped doing that. And he use to right long paragraphs and say I Love You but now it's either u 2 or just love u. I feel like he's not romantic and everything because He doesn't feel like he needs to, doesn't need to woo me, because he already won me and has my heart. Any advise on how to make my boyfriend want me and become more romantic? Please!
