A girl liked me and we where texting for 100 days and she admitted that but removed me from snap?

Okey i need a help to understand the situation there was a girl in my school we talked a lot on snap and we liked each other we met once and she very shy. We where snaping about 100 days talking about sex and everything. we had kind of decided that I was going to her but i said (it was planned) i missed my last bus and I couldn’t make it to here in other way. In the school we had eye contact but i didn’t get chance to talk with because of she was so shy. So after missing the bus she got a little bit mad at me but it was ok but after couple of days she started to get cold and removed me on snap and no more eye contact in collage. Should i text her on instagram and what should i text to her or just block her on insta
