Do you guys ever go through phases where you don’t find your s/o attractive?

i’m 33f and lately i have been going through phases where i am very much not attracted to my boyfriend (31m). it’ll last about a week or so and then be followed by a few days of intense attraction.. and then back to not being into him or not wanting to have sex. i still love him, but this cycle is making me question the relationship. we’ve been together for 3 years and this just started happening in the last year. i know couples go through phases of good times and not so good times, but this is pretty consistent. and it may very well be a me problem, perhaps some sort of mental health stuff going on. but i will say, he does not work at this time, and just kind of couch rots/plays video games. i think he is also depressed. i’m concerned we are heading in a bad direction and im not sure how to get back to the good times of being happy and intimate. advice welcome.. no need for sarcastic/rude answers.. i am aware i can leave him, but i dont want to give up just yet.
