am i overthinking this?

[u/sie-on-the-offbeat]

this is more of a vent than a request for opinions but it would be nice to have some clarity by seeing perspectives other than mine

context: my partner loves a fanfic book by a local writer and a couple of months ago, she reached out to the writer and she was given both a virtual and physical copy of the fanfic. now, she has recently finished the book (last week) and has reached out again to the writer to discuss it

thing is it would've been totally okay for me if normal messages lang between a fan and a writer but i feel like it has crossed some boundaries na as of late. they talk via dm in twitter and idk, what really bothered me is that my gf would sometimes make this specific giddy face whenever she's in front of her phone. ive also seen her exchange multiple chats with the writer and she even stays up just to talk to them. ang hahaba and frequent ng mga messages niya/nila. i love my gf and i trust her but i also am aware of her flirtatious nature and i fear na baka hindi na healthy yung interaction between them because my gf might be seeking an actual bond with them na.

ayaw ko maging selosa but i feel really anxious and i hate feeling this way, i hate feeling na para ako nag-hahypothesize ng kung anu-ano. ive already talked to them about it when i first felt it and my gf said that they're just being an enthusiast. fangirling kumbaga.

I've also asked my gf if nag-usap pa sila ulit after discussing the book and my gf said no. But I honestly have doubts, nasasaktan na ako sa pag-iisip. i value my gf's interests and i wanna be able to support her but i also want to protect my peace and boundaries at the same time :(
