<human>: Summarize the given text in a few sentences.

I met this girl (17), let's call her Anna, at work a few months ago. She started talking with me and she was really nice, friendly and I enjoyed talking with her, so we soon became somewhat of friends. We found out we live on the same street as each other and she offered me rides to and from work when we worked the same shifts (at the time I didn't have a car). Soon after I began to realize my feelings for her. Anna invited me to her birthday bonfire, which was a blast, but we didn't talk a lot. She apologised later for this by saying, "Sorry we didn't talk much, we work together all the time, so I kinda wanted to spend more time with the other guests." I said it was fine and that I met some new friends anyway. A few weeks later she invited me to a Canada day/last day before she goes on her volunteercation bonfire. I said I'll probably be there, but when I asked the friend I went with to the first one she had he said he was also planning a bonfire and wanted me to come. So I told her something came up and I couldn't go which she seemed disappointed about, but said was fine (I should mention here that I mostly didn't want to go because I didn't want to be that guy at the party who doesn't know anybody). So I went to his which he invited the girls we met at the first bonfire. We started driving around and they brought up the idea of seeing Anna at her bonfire. I told them I didn't want to go because I'm a shy kinda awkward guy and I thought it would be awkward. I ended up going down, but Anna and I didn't talk much and we left pretty fast. I haven't really talked with her much since then because she took off the summer for trips. I don't know what to do and I could really use some advice.
<bot>: Started to work with a girl, began to like her, went to some parties, don't know what to do from here.
