Am I just being realistic and reasonable or is it the trust issues?

Saw I saw this girl on instagram a while ago prettiest girl I’ve ever seen in my life and I really wanted to shoot my shot but she ha like hundreds of thousands of followers. Dming her wouldn’t have worked especially with instagrams stupid new restrictions they put in Dms and even following someone now. i see this girl had an OF she had a sale and me wanting it that bad joined her page to shoot my shot. At first she refused to even take things off the site seemed like I fumbled which is fine 12$ isn’t gonna hurt my pockets. But then one day we really got into a deep convo and it really I don't know clicked it felt like after that she always seemed excited to talk to me she even told me she loved me on more than one occasion. Would send me goodnight I love you texts she became really supportive would worry about my health if i would mention I wasn’t feeling well. Even off platform on her ig when if post she’d like and reply to all my comments which is a lot considering she had multiple back up ig pages in case she has issue with her main or it gets taken down she even followed me on those pages. And she even said she wanted to see me at one point mind you we live in different countries. But lately she talks to me less and less, stopped likening and replying to most of my post on her ig pages some days I’ll text her and will just get no answer when she is online. There’s obviously been a switch up I haven’t asked her about it yet not sure if I wanna here the answer she does still say she loves me when we do talk. But it all just feels so artificial like she’s saying that to just keep me subbed to her page if that. My sub to her pages expires today gonna let it run out and take a step back and also see what she does how she reacts. If it doesn’t go in my favor oh well ig part of me was always skeptical to begin with so no big blow to my ego but a big one to my heart searching for love in this fog of heartbreak is discouraging bro say the least.
