it’s this a red flag ?

so i made this friend a few months ago. we hit it off because we shared a negative experience with an organisation and we were so similar. But she’s a bit more “clingy” than i’m used to other friendships being. She replies within seconds sometimes she’s in the chat when i reply even if it’s like an hour later as if she’s sitting waiting for my reply (it’s not snapchat so it doesn’t give a notification if i’m typing). that’s not really weird until you add in the fact that she’s literally working full time, married and with a child under 5. how does she have the time, every time to reply that quickly? if i don’t reply within a certain time she send another message sometimes on a different platform. recently i’ve noticed that (not exaggerating) she views my tiktok profile everyday. sometimes multiple times a day. A couple days ago she was like “i stalked your profiles, i was bored haha”. it’s starting to weird me out. there are other instances where it’s clear she’s quite insecure (but i just put it down to past experiences with other people) she said other ppl have rejected her friendship and i feel bad to slowly drop her too. she’s a cool person other than the stalking, but there’s normal “one-time-only-see-what-this-person-is-about stalking” and then there’s weird stalking. friendship red flag or should i look past it?
