I'm in love with my bestfriend but she is technically in a relationship. How do I handle this?

Ok so sorta a weird explanation. I met her about 9 years ago in high school and within a month or 2, I wanted her to be mine. She was dating this guy so i said fuck it, I'll settle for just being friends. Fast forward a bit and her and I become best friends. Even got a bestfriend date and handshake. Feelings for her keep growing by the way.

Ok well fast forward a bit more, like 2 years and we end up doing the dirty... a few times but keeping it on the low for now. Turns out she had a thing for me too. End up calling it off because we didn't wanna ruin this perfect friendship we had.

Fast forward to about a month ago. I've dated a bunch of girls, she's dated a few dudes. But now she's in an extremely toxic relationship with this guy for the last 3 or 4 years. Only reason she hasn't called it off is because she's living rent free with him and his parents while in school. He cheated on her with several other girls. He said it was because she got fat. Now she gained like 20 lbs but this dude is fat as fkkk.

We hung out the other day and she was telling me about how annoying it is and after spending about 45 minutes in the car just talking, we start making out. Like super passionately. Happiest I've been in years tbh. Same thing happened the next day. Few days later, she comes over to my place. Was about a 2 hour drive for her but I've been driving to see her every weekend so whatever lol.

Took her out to eat, took her back to my place so we could chat, watch movies, and introduce her to my cat. Well we end up doing the dirty dirty a few times. Kinda embarrassing but I lasted like 20 minutes with her which for me is kinda short. Last girlfriend I had, I'd last for like an hour or so

Anyway, she tells me that that was the happiest she has been in a while too.

But then yesterday, she tells me we gotta stop what we are doing. She's scared of getting kicked out if he finds out. I plan on moving closer to her (it's for a job) and told her to move in.

Wtf do I need to do now?
