Sexless relationship, what to do? 27m 28f

and 28 F My partner (27m) and I (28f) have been together for almost 2 years and have not had sex in over a year. My partner never wants to have sex or anything sexual, when it's been brought up he just says that he's "just too much in his own head" "sex isn't important to me" or brushes it off. He's not into giving or receiving so I don't know what to do. I'm definitely not the most sexual person however, would like to have some intimacy on the rare occasions (minimum once every couple months). It's gotten to the point where i feel he isnt attracted to me, my self-esteem is almost diminished and mental health isn't the greatest. This may be a bit of TMI, the last 2 times I've had "me time" I cried after, maybe as I've come to the realisation that I'm setting myself up for a sexless life with this man?
