Why does my ex girlfriend's best friend stalk me online?

[Anonymous]

Long story short, my ex dumped me and cut off contact months ago. I initially disturbed her a lot, trying to reach out to her but she didn't respond. I surprisingly talked everyday to her best friend and even she got pissed off and told. me to stay away from her.
2 months later I wrote a text and apologized for the way I behaved and ended on a goodbye, and she finally replied so I sorta got the closure. I know I wasn't exactly at fault, everyone said I was the nice guy, and she replied because I sorta blamed myself in the text but I had to make peace with myself.
She did sorry for the way it ended. The thing is, that best friend of hers? She stalks me online quite frequently, and it initially didn't matter. But then it just sorta increased. I know it's not my ex, because they don't share each other's passwords, but why is her best friend so keen on knowing everything in my life. We don't even follow each other. And initially I was blocked by her too during which she would unblock me and watch my story and then block me. again.
Why is she stalking me so much?
Girls, have a clue?

She's checking up on you for her friend, she decided she likes you and/or she's 16 years old.

Likes me in what way but?
Also I forgot to mention, she really didn't have any feelings for me at the time of the breakup. It was almost like she didn't care. That's why in curious as to why her best friend stalks me so much

[Asker]

And hahaha she is sorta 17

[SarahsSummer]

I figured. these issues don't generally occur with 45 plus aged men/women. It's pretty much a high school thing. Why would you say your are in your 40's?
Also, now I'm confused. Who didn't have feelings for you at the time of the breakup? Who didn't care? Your girlfriend or her friend?

[Asker]

My girlfriend didn't

[Asker]

But like her best friend stalks me quite often for some reason who knows

[SarahsSummer]

So pursue the friend and see what happens.

[Asker]

That best friend was the person I basically talked to after she broke up with me, and her and I ended on a bad note cuz duh I'm talking to my ex's best friend. Infact she literally was the rudest person.

[Asker]

She even blocked me but unblocked me a few months later and stuff

[SarahsSummer]

Childish behavior all around. Just move on, ignore them both and focus your attentions elsewhere.

How do you know she's stalking you?

[Asker]

Basically, I don't have a ton of followers on Instagram so I can easily see anyone who views my stories and her name pops right up.

[Asker]

Oh and im 18 years not 50

[LeahParis]

Oh I see. Do you think she knows that you can see her viewing your stories? Maybe say something to her next time she sees your stories like ask her how she's doing or something like that to see her reaction.

[Asker]

Dude I can't, her account isn't public, mine is, why tf is she stalking me when everything got over months ago and nobody gives a damn?

[LeahParis]

Like shit calm down chill I was trying to help you! You can still reply to people even when their accounts are private. Anyways you sound mad and I clearly can't give anything else that could help the situation. Time to leave now. Good luck it that.

[Asker]

Well I am calm but you can see the fire in my words because I'm genuinely riddled

[Asker]

It's better if you have a definite answer
