I recently met a girl named Jane in December last year at a friend's party. We hit off really well after a few weeks and we would talk to each other a lot. It was the holidays so we would go out with our group of friends quite a lot, meaning we get to see each other a lot. She would talk to me the most out of the group and would always sit beside me when we were eating or watching a movie. She would also text me and call me everyday. We would call through the night and fall asleep on the call every night. She has depression and would tell me most of her issues and would come to me whenever she felt sad or had suicidal thoughts. She told me a lot about herself, stuff like her cutting herself or family problems. Even after school had started, she would call me the moment she reached home. However, she suddenly started texting me lesser and lesser, and would only call me late at night for only a short while or sometimes not at all. She also takes unusually long to respond to my messages or sometimes will just ignore them. She rarely starts conversations with me anymore and feels really distant. I'm not sure if she's angry at me and I care about her a lot and I really don't want us to drift apart. It feels like a punch in the gut when she ignores me and I really want us to be close again. Any suggestions?
