It's normal to tell my best friend that i love her
So the question here is I've been talking to her for about 3 and a half years and she's the only friend I have, since the beginning I felt something for her, we stayed nights talking until dawn and it was very pleasant for me, only that then we stayed a whole year without talking and we started talking now again at the end of the year 2021. She had a boyfriend at the time but she already broke up with him, I don't know if she sees me the same way, because when we talk she is super cute to me, only lately she's been taking a long time to respond, but she apologize for that and I understand she's been very busy with schoolwork, but i also try to score something just that she avoids as much as possible and never wants to show her face when we talk online by call. What should I do?
