My fwb

So me(now 16, F)and this guy( now 18, M) where dating back when I was in 8th grade and he was in 10th. We spent that year together but when I was in 9th grade and he was still in 10th(he repeated), he cheated on me with a girl in the 8th grade, and when I confronted him, he asked for "us" to be in a Polly amorous relationship but the thing is he only told me and not her. I really liked him and was willing to do anything to keep his love so I agreed. After a while I caught on to the fact that I knew but she didn't know which made me look like a fool and showed more respect for her than me tbh I didn't respect myself to. I went through a self loving journey and decided to break up with him

Down the line I am in the 10th grade and he is in the 11th, and I don't really pay attention to his relationship status!. We hadn't spoken in a while and we live in the same neighborhood, so there was a party and we decided to run around the party together because we are both extroverts, and we remembered how enjoyable it was speaking to one another, that night he broke my virginity. Btw apparently he got back together with that same girl(now in 9th grade) he cheated on me with.

Don't ask how but we are fck buddies now and a few days ago we were together I felt like he was developing feelings again for me or maybe they never died. This worries me because our relationship was toxic and painful, but I still want my dose of dck from him no one else because he is the one that broke it

Question is what do I do to still get my dose of d , but not fall for him( because I still love him and I would love to be in a relationship with him but I'm scared that it's going to be just like last time, in all fairness people change and grow so I believe if we tried a second time it might work, idk😐) please someone help, sorry for the paragraphs
