Confused Bout My Crush

Just got of the phone with my best friend.
She called me during lunch since we both do virtual school. We said out hi's and then, I quote, she said "Its nice to hear your voice." I panicked. I PANICKED LIKE THE BI PAN IDFK ANYMORE FOOL I WAS. OH GOD IS SHE GAY/BI/PAN? AM I OVERREACTING? YES! AM I INTERESTED IN HER? She laughed awkwardly and then started saying something and then I snapped out of it and interrupted her.
"Same, yeah yeah its nice to hear your voice too. Especially after so long. Yeah." I sounded like a fcking dork. Then we both giggled and moved on. We talked about the US election because that's funny and entertaining to talk about and when I hung up my mom walked over and touched my cheek and said it was so hot. I then realized I have been blushing for awhile and my cheeks and burning. OH GOD HOW AM I GONNA EXPLAIN THIS??? I said it was probably because I was kinda holding back my laughs. YES I DON'T HAVE BRAIN CELLS AND SUCK AT LYING APPARENTLY. And then I was reminded of the dream I had a year ago. A dream where I kissed her and dated her. FUCK. NO. SHE. IS. JUST. A. CLOSE. FRIEND. AHAHAHA FUCK THE FIRST TIME I THINK I LIKE SOMEONE IT HAS TO BE MY BEST FRIEND. AND SHE'S CUTE. AND PRETTY. AND SMART. AND ATHLETIC. AND OUT OF MY LEAGUE. AND JUST A FRIEND? AND MY MOM TOLD MY DAD ABOUT HOW I WAS BLUSHING AFTER I GOT OFF THE PHONE. I HAVEN'T COME OUT YET. DO THEY KNOW? ARE THEY SUSPECTING? AHHHHHHHHHHHHHHHH. what do i do? do i like her? and do you think my parents have figured it out? (╯°Д °)╯╧╧

So, my ex (let's call him Z) and I broke up a year ago, but lately I find myself thinking about him and just seeing random things that remind me of him.
When Z broke up with me (over text BTW), I wasn't sad or anything. I was just like, "Meh. whatever." When he joined my math class in the middle of the year and we started talking as classmates again, I started falling for him again.
Now, we're stuck in quarantine and I haven't seen Z for months, but I've been dreaming and thinking about him for a while now.
Do any of y'alls think it's okay for me to like him again even though he broke up with me with one of the worst ways or should I just move on? ╥﹏╥
