What do i doooo

So! ive now been with my bf for like, 5 days. yay! love him but the thing is, im not completely over my ex, WHO btw, im still friends with. and he's also friends (ish) with my bf ex is now O bf is W the reason O and me broke up was because he found out he was Lithromantic! which is completely fine- he cant choose that. it just hurt, a lot. its almost a year (9 months) and it still hurts, i still love him. i get sick to my stomach at things that remind me. capcut in general, certain songs, talking to him, memories. I've been trying to get over it recently. and i really do love W. but when im on call with him- i feel like a terrible person (not cause i still love O- hes aware of the problem) because he reminds me of O so much. his laugh, how he speaks, his strange interests, even his appearance. if they went out together (not like a date-) people would assume theyre siblings! and it makes me feel terrible, panicking that i actually dont like W. and its just me circling back to O then last night i was talking to O, and he's trying to cheer me up (yesterday was a bad day) and he tells me he recently got with someone. i- i dont understand. im happy for him. i think! but i thought he was Lithromantic? thats why we broke up- because he lost feelings for me because i liked him back. im hurt, confused, and i feel so sick, and jealous. but then i have to remind myself that im with W. and that i love him. I DONT KNOW WHAT TO DOOOOO (not a vent, more like a rant :/)
