So here's the situation. I just started college and met this girl from my class. I don't usually talk to lot of women so this is new to me. I asked her about course work, beat around the bush and finally asked her snap Id. I never used to chat with girls but this time I did my homework I thought about topics to have a conversation and be interesting. But she on the other hand does lot of Chatting she had a snap score of 70k+ and me 3k.

We chatted ALOT. We had interesting conversations for 3 hrs straight every time. I was the one who mostly sends the first msg and prolongs the conversation but she is also interesting and responsive (I would get replies within minutes)and she would send voice msgs too. Then we became besties in Snapchat with the yellow heart thing on side within 10 days from the time I first texted.

Kaboom

Things started going down hill then idk what happened she wasn't responsive anymore. She was the same person who told that she enjoys chatting and is 24/7 online. I was ignored and ghosted. She removed me as her friend from snap and texted back saying that it was a mistake and added back. The yellow heart thing was gone. She even stopped looking at my snaps.Now all there is is late replies and dry af texts no real conversation after 2 weeks. She doesn't even look at my snaps like wtf. When asked she told that she will open when she is bored.

I am sure that I did not make her feel uncomfortable, insecure or offend her in anyway. But I did ask her about the late replies.

TL;DR Girl I met at college ghosted me after having good,interesting and long conversation for weeks and I don't know what's wrong. She doesn't even care to look at the snaps I send her, it makes me feel pretty uncomfortable.

Edit: We'll be in the same class for the next 4 years.
