Why do I feel no emotions or attraction to any guy anymore?

I’ve been depressed for few years. I’m almost 30 and never had a boyfriend. When I was younger I used to get butterflies & excited for any handsome guy. But even if I talk to a random guy per day, I feel nothing. I don’t care for them, I’m not clingy, I have no interest.
the only guy that dated me was a guy that used me as a friends with benefits and I thought he was my boyfriend. In that time I was in love & he wasn’t. I had joy dress up 4 date & high sex drive 18-24.
I haven’t had a date, or sex or kiss in years. Few guys I try meet only wanted hookup & I want a boyfriend not hookup.
the last guy I had deep attraction to was 2 months ago & he already had baby & girlfriend.

so now I feel nothing. I need a partner but don’t love any guy, don’t feel attraction.
