Need a help because of issue with contacting one person?

[Rodeo332]

First of all, I'm sorry it is mixed as a private problem, I think it wouldn't be a big problem.

Ok, so I would need a big help / advices here an I'm really gratefull if somebody would tell me what to do.
I would also feel free to ask some subquestions.

There is one girl from my elementary school. Let's name her "K" for easier following.
I know her from when I was 11 years old; she is one class younger than me; I'm now 19 and she's 18. She is also daughter of my mother ex-boss (employer who has his own corporation long time ago).
And for years and years I just want to make small contact with her, I wat her not a big things, just to help me about some information stuff... but I can only ask her these things, because I know that only she can give me best advices in these cases... Once in life we had small 10 minute conversation.

And I'm trying to make contact with her more than 2 years from now, but nothing.
1). First, I was send her Facebook request, but she didn't accepted it.
2). Second, I contacted best female friend of "K". And I was polite, I asked would she be that nice to tell "K" that I need her for one information. Her female friends told me: "Yes of course, but not right now, she's over-occupated at this moment, so I will tell her that you need her."
3.). Couple days later, I checked Facebook profile of "K" and I saw that she joined to Facebook group: "I hate when people constantly adding me, or ask my friends may they add me."

I thought that there may be possibility that she founded that my mom works for her dad. But it still doesn't make sense... I will not kill her if I just want to ask few simple advices

Second of all, my mother has telephone number of her mother. So I thought maybe will be good idea if I ask my mom to ask mom of "K" to add me, that I only need few informations...

Excuse me for long, but these are my questions:
-Is there any possibility that she founded that my mom worked for them, so from that reason she doesn't wnat to have any kind of friendship with me?
-Is it stupid idea to talk with my mother to talk with her mother?
-Is there any other possibility how can I contact her? She lives pretty much far from me.

Thank you very much.

I don't mean to be harsh but clearly she is not interested. So you should leave her alone and let her speak to you if she is interested.
Second it is super silly for you to ask your mum. Are you sure your 19 because honestly a 19 year old bloke wouldn't really bother. Finally you should stop trying to contact her before she complains of harassment.
