Please help‼️‼️😞😞

How do I get my boyfriend to be crazy about me like he use to be? We’ve been dating for almost 13 months now and he had excellent energy months 1-5 but after awhile his efforts slacked.. my energy has stayed the same since we started dating.. he hardly puts energy into texting and shows a little more energy in person but it takes me begging him to post me, begging him to see me at work, and he constantly promises to ask him mom why he can’t hang out later with me but it’s the same excuse “she’s asleep when I get home” “i don’t want to text her” he’s always okay with days he doesn’t see me and says “it’s just one/three/five day(s)” what am I doing wrong? Is he losing interest in me..

He’s 17

I’m 18
