am i overthinking or is it something worth worrying

hey, hope u guys are having a great day.

so ive been talking to this someone for about 4 months. i dont know much abt them personally but from the small bits of info ik theyre amazing and i just wanna talk to them 24/7. ive never really experienced a crush for someone, truly the last time i did was when i was in primary school. im scared that i might be annoying them cuz they never message me first. its always me starting the convo; and when i do sometimes they just give out short answers and we end up having small talk. im scared that they no longer feel anything for me or realized im not worth it. i wrote them a poem for valentines day and they said they liked it. the thing is im scared they lied and said that so i would shut up. im scared that my lack of skills was a turn off and now i dont know if i should show them the other poems/letters i made thinking abt them. but then again, they did say that i meant something so idk. i also try to defend them by telling myself that maybe they could be busy and have stuff to do i hate feeling like im annoying them but i js wanna talk to them. i just wanna be with them. i dont think theyve given me much reasons to overthink, ig its just my fear of not being enough for someone.
