No sex drive anymore

So to start off me and my boyfriend have been together almost a year now and for the first like 6 months my sex drive was high all the time we were doin it multiple time a day sometimes and usually everyday and then it kinda just slowly started to fade out to now we rarely have sex. I feel like i can’t really ever get in the mood sometimes and thank the lord he’s a great man and never complains about it or makes me feel pressured into doing it but i just feel bad sometimes bc obviously he’s a man i know he wants to and i do too but i just can’t seem to get in the mood to do it. Is this a normal thing? I feel bad bc now we rarely ever have sex and i’m an over-thinker so naturally i question will he get bored? Will he look for sex somewhere else? I don’t think he would he’s very respectful and i know he loves me but what can i do to get my sex drive back?
