Relationship advice

I love my boyfriend and he treats me like a queen, but recently I feel myself trying to push away. Like I don't want to see him and don't really wanna talk. I feel myself getting annoyed. I really do love him but I don't know why I started feeling this way. Please don't be rude and say that I don't love him because I do. I can see myself spending the rest of my life with him. I just want to know why I will feel this why and if anyone else has.
