So this former oneitis of mine texted me last night randomly, we used to talk a lot most of the time i would text her and she would text me after hours, for example i texted her last month we talked for a bit but then she stopped.
She annoys me sometimes because she does that a lot. So she says
"I'm still awake... And I have school tomorrow... How hardcore am I! Impressive or what?!" talking about me sleeping a lot.
Is she just bored? Is she looking for attention?

Btw we're childhood friends in some way, but i live like an hours flight from her so i can only text her or video call her. What should i do ignore her?
Sorry its long..

Just ignore her. Distance would be a factor anyways.

The only answer here is for you to learn how to talk to both guys and girls without wanting anything from them. And enjoy the conversation.

You guys contradicting each other doesnt help...

If you want something out of her, don't bother. As Migster said, the distance issue is too large to be worthwhile.

If you just want someone to talk to which is perfectly fine, continue the conversation. No big deal.
