After telling the girl that I like you, why did she ignore me, not answer the phone or return the text messages?

According to what you said, she may not like you for a while and don't know how to face it, so she took an evasive attitude. Give her more time. What is yours is yours. It's no use rushing. If you like people, people don't necessarily like you. Life is so helpless. The person who loves me is infatuated with me and I don't regret it, but I shed tears for the person I love ... Love is the most unreasonable thing, so don't play cards according to common sense, just get used to it.
