My straight friends think it's funny to joke to me

I (16F) came out when i was 14, I have had this experience before when my crush as a "joke" told she loved me and then when I asked her about it later (because I thought the feelings were genuine oh how dumb of me to believe it when someone said I love you to me 😭) she told me she didnt remember and must have been a joke. It was not a joke to me I cut off ties with her.

Well this happened again. My friend (16F) whom I think of her as a friend only, started randomly talking to me about how she wanted me to "uncrush" from my crush (basically move on because my crush is straight) and wanted to be in place of my crush. I tried explaining to her that she would reject me as well because she is "straight". So she proceeds to say, "who said that?" And I was like, "Are you kidding with me?" Because I don't like jokes like these, they make me feel insecure and unloved. And she proceeds to say "I am not" and i still did not believe her. And then i asked her, "Why did you mean by that?" Her reply was "By what?" And I asked her, "our talk before" and she was like "I have dropped way to many hints" with a damn smile. WHAT AM I SUPPOSED TO THINK DUDE So i understood that she might have a crush on me and I guess that's her way to confessing and i was on 7th cloud not even 7th, 8th 9th wtv. But then this reminded me of my previous friend who did the same to me and I started panicking. And my friend understood im acting nervous all of a second and wqs confused on what to do. So when i ask her the last time, she explained everything.

She was joking with me. She was straight and didn't like my that way. I was crushed, My friend thought it would be funny to joke about that just because I don't have any boundaries. She started apologizing, "Im very sorry, i was gonna say- Hypothetical situation, if i was not straight, I wouldve dated you" This added salt to my wounds because all of my crushes have said that.

I have recieved messages from her about how she feels sorry and i have just asked her the reason why she did that and she told me that she would explain it to me when we meet 3 days later in college. Lol I wanna cry
