Why his behaviour changed after sexting?

i like a guy. he has been texting me for 3 months. he used give me importance. he used to text me throghout the day. few days ago he asked for sexting. i said yes even though i was not comfortable. for his happiness i said yes. now he only texts at night. and whenever he texts there is no affection like before. he has become cold towards me. whenever i do not reply to his sexual questions he get annoyed and he says bye. i feel so anxious. what can i do to make our friendship like before?
