No sex drive😡

My boyfriend and i have been together almost 3 years, and we used to have sex almost every day, it sounds cliche but since i started working over a year ago it decreased - not by much but a little, but over the last 5 months i have not had any urge to have sex, i want to?! But i just dont feel it, anything i can do to sort this? The last time we had sex was a week ago, but before that it was a whole 6 weeks, and i dont feel as close to him as when we did when we had alot of sex. What can i do to get my sex drive back?
