So I had this friend since last year. We were super close, like sisters. We would hang out anytime we could. Then there were problems at school and she decided to switch. I was rlly sad but supported her opinion. So she switched this year and we only have talked a few times. We have hung out twice for each others birthday. I felt like we didn't have that spark anymore. Then I have tried txting her a few times and she hasn't responded since Christmas (ish) and I have a feeling she blocked my number and doesn't want to talk anymore. We were supposed to see each other to give Xmas gifts but she never responded about a date so I still have them in my room waiting in a shelf. What should I do??
