Is He Changing For Me?

So my ex used to be very un appreciative, mean, and selfish. He is veying "Dominant" over me. But lately, he went from being an a** to being patient, concerned, nice, etc. Like we were talking and i told him how girls were telling me to get facial percings and he said "no, that will mess up your face. They are just jelous cause of how beautiful you are" he hasnt said i was beautiful in a looooong time. And when i asked if i should just go back to the way i was with him, he said "no. Not because i dont want you to because i miss you like crazy, but you just started talking to me again and i dont wanna mess this up" *i had stopped talking to him for just a few days* did he change for me? Or is he being a kiss up?
