Do I still text this girl or not?

Send her a text that says, "Let's get together for a coffee. Say, this Thursday?"

And see what happens.

Hi Jespah,
I asked if she would go to costa with me and she said she didn't know me that well. What should i do with that as we have been on the same bus for the past 4 years.

I don't know what costa means. Is it an overnight stay? Costa Rica? Costa del Sol?

Hi,
It's a coffee Shop chain in England.

Ah, thanks.

Well, if she can't commit to coffee then I would say let the connection slide. If she's interested, she'll contact you.

In the meantime, have fun with your friends and live your life. If it's meant to happen, then it will (although I have to say, I think the odds aren't looking so good, sorry).
