I need my sex drive back😫

Lately my sex drive has been almost nonexistent! I live with my boyfriend and our work schedules aren't exactly in sync but we could definitely block out time for sex if we want to... the only problem is, I haven't wanted to in weeks and I dont know why. I need tips, tricks, advice, anything because he understands and doesn't push anything on me but I know it bothers him a bit and honestly its bothering me too because I used to have such a high drive. Long story short, HELP😭
