<human>: Hello everyone. I met someone and want some advice as how to proceed. 

Last Friday I met this american girl at a party. We talked for hours (about Star Wars, Rocky and Refugee Law aka best convo ever) and had a few drinks. Since it was a rooftop party we when to have a view around us and we kissed. Before we did I asked if she was in a relationship (as any form of cheating is an absolute deal breaker for me) and she said she was single but it was complicated.

After a while, we exchanged numbers and I walked her back home. We kissed again before saying goodbye.

At this point it sounds quite good however ever since I haven't heard of her. I texted her once on Saturday to no response. I added her on fb and she accepted the request, afterwards I send a message on there with the same result.

Finally yesterday I tried calling her cellphone, but it goes directly to voicemail. 

Should I try to keep reaching to her? Is she ghosting me? I hate the fact that if she has no interest in me she doesn't say anything about it.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: met a girl, told me she is single but it's complicated, we made out, exchanged numbers and I haven't been able to communicate with her.
