need help to kinda sort my feelings

so i have 2 exes now, i'm a female and both of them were male. the reason i broke up with both of them was because of a similar reason, i lost feelings not even 2 weeks into the relationship. i don't know the reason why like they were both amazing and kind people, i was the one who approached them and we had alot of fun time together too, like talking about our interests, sharing our fav music albums, playing games etc.

after a certain point into the relationship i felt guilty for saying i love you when our feelings weren't mutual, i even used to find them annoying when they act even a bit clingy (even a ''how are you'' or ''what are you doing'' in between hours felt bothersome to answer like a chore)
i even had to lie saying i didn't like men anymore to my first ex so that he wouldn't feel bad about the break up

like idk what's wrong with me, i fall in love really easily but at the same time i lose interest really fast too and i labelled myself as bisexual or maybe pansexual bc i wouldn't mind dating anyone as long as the feelings are mutual but idk anymore man sometimes i even felt like i'm aroace but i did kind of get in bed with a girl before and liked it very much

i tried to like a girl too but most of the time it felt like i was forcing myself to feel that way with the girls close to me for the sake of ''experimenting''. i mean i can imagine myself with any kind of person as long as our tastes match and enjoy each other's presence but idk...

who di i even like??? i definitely know i'm not straight that's for sure lmao
