What’s it called when a guy turns on you?

We used to be friends he is gay so that’s how I know we’re just friends

He just turned on me on day telling his boss I had more feelings for him

I Would just book certain gym classes just so I can be one on one with Him

he used to be so nice to me make me feel nice tell me to stand up for myself

he used to text me and tell me that there is no one else booked into certain classes if I wanted to come down to the gym etc

im kind of hurt a lot over the whole thing
