I want to get back with my Ex but idk

I had been in long distance relationship for 6 months. He loves and adore me a lot. He always says am pretty and always says I Love you in video call until I say him back. but I never say him such thing. I came to New York 5 months ago he is also here but he is in different state of America. I was busy so I didn’t get time to talk with him but he still loved me. He went back to his country and he is little bit only changed but I broke with him. He said to me “should have know you better’ and I cried almost everyday. I really miss him even tho I am really bad person infront of him. All I want is his happiness.. I wanna get back again but he talks so rude.. now.. maybe because he is angry with me . But I just miss old him 😭😭😭
