Being Accused Of 1st Degree Rape?

So a year ago me and this guy were good friends, we live in the towns right next to eachother, and eventually things became more than friends. I wanted a relationship he didn’t wanna jump into anything, but said he was interested, so it was just casual flirting for a bit. Fast forward a couple weeks maybe and I’m fighting with my parents and need a place to stay, he says I can stay at his buddy’s house with him for a couple days so I did. It was chill most the time, but whenever we were alone he’d try to hold my hand and lay on me and all that shit, which admittedly I was into since I thought we were a thing. So ofc those little things led to more and when everyone left (accept a girl that was literally in the next room over and there’s not even a door) then me and him slept together. Day after I find out he’s talking to another chick that’s definitely more attractive than me, and when I asked her about it she had no idea about me, and he told her that he regretted doing anything with me and blocked me. Fast forward to now, I tried to be chill with this guy after everything because we had the same friends and I’ve never been a confrontational person but we still just didn’t talk. He’s now dating a girl that I used to be friends with and this girl has been hung up on him for so long cuz they dated years ago. So as of now I suddenly got kicked out of the group and it’s because he told them I raped him in his sleep at his friends house. I just really need to know if I can take any legal action with this because I never thought that me as a female and an actual survivor of sexual abuse to be falsely accused by a grown man. Like this to cover his ass for some sick reason.
