I'm special & always make her smile, now she won't talk. What should I say?

[Sci-Man]

First of all, thank you for reading this, it is much appreciated:

On a summer holiday, I came across a girl from the hotel who found me on a social media site, despite not talking to each other (she came on holiday not long before I left). We are both college students (I'm a year older). We have spoken to each other almost every day for 5 months via text message & occassionally skype. She's smart, nice, cute, and she feels special to me (unlike most girls that I have known). She smiles when I speak to her & seems happy.

We've been very close for those 5 months, and I really don't want this to end. Recently I asked when would you like to meet up and she said in the summer, which I agreed to as we have exams before-hand. I said it would take time & I want to take it slow as it's difficult, but we can do it, and I might be moving not far from her to a University in September (possibly). She seemed shy about it & barely made eye contact.

She said i felt special to her & always make her smile a few weeks ago. We've talked for ages & I've been nice to her, when she was down. However, It turns out she is lying:

I was talking to her on Skype whilst she was messaging someone, which I found rude, & I have a feeling it's someone she likes, and she has been recently distant with me (stopped making converation) so I knew she was up to something. She has said I trust her & she trusts me, but now It seems that she's broken it. I asked to call her, she said she is busy, and says it more commonly.

So, she doesn't know how I've noticed she's liking him (if true), so I'm thinking of calling her tomorrow in a normal conversation, and then explain this. What should I say & do? I've put so much effort into this and it seems like she just wants attention, I don't want to give up.

Just ask to call her that it is ¡¡¡VERYYY important!!! When you guys are on the phone, just have a heart to heart convo, and tell her the truth. Tell her you feel you guys are too distant... Just be honest and see how it goes from there
