Im [15F] and not sure if my ex still [15M] still has feelings for me.

so my ex and i broke up 2 weeks ago and it came out of the blue, even tho we were having issues bc i cldnt rly text much due to some personal things but things were rlly good that day in skl but later in the evening he texted saying things didnt feel right and he felt it might be better to js break up and i agreed saying i felt the same bc i didnt want to seem desperate if he made up his mind. i saw him in skl a few days later and i felt terrible bc of how awkward it was and i mainly blamed myself for it.

but the next day js when i thght maybe things wldnt be so awkward btwn us, someone told me that while we were dating he'd been talking and flirting w another girl and i didnt believe it at first bc he was always such a sweet guy but i remb overhearing a convo between him and his friend the day we saw eachother aft breaking up, and he was talking abt how he "wanted to keep both of them" and his friend said it would be too selfish. so i didnt rly know what to believe and i asked him about it the next day and he denied flirting w her he said they were friends and they talked but they didnt flirt and he wrote me a long note basically just saying the same thing i guess except in the note he didnt deny it outright he said things like "we were talking but that doesnt mean we flirted" and "forgive me if you think we flirted" but everyone told me that theres no way hed actually cheat.

and this week i heard rumours that he was dating someone else so i asked my friend to casually ask if he was but he said "u think i can date any1 after her, the one i love" and he basically said he doesnt think he can ever date anyone after breaking up with me, but im not sure if he said that bc he knew the information would get back to me or if he actually meant it. and during class he accidentally threw a paper at me and got rly embarassed and all smiley and i saw him smiling at the paper aswell later?? and theres other things that make me think theres a chance we could get back tgt, and i rlly want to bc i know i can make things work out if we do get back tgt. but idk if there even is a chance anymore.
