Does he want to leave me?

We have been dating for almost a year. Last two weeks he doesn't talk to me much, sends me 2 messages per a day and miss spell like written in a hurry... He said he is busy with work. Even on his birthday he was busy and just said I love your gift thank you and nothing else. I noticed he shared my favourite movie with his girl best friend, he also follows a lot of girls on social media... I kept brining things up to him but he calls me overthinker and crazy for not trusting him. Even tho keeps repeating same action. He answer me early mornings and he said he came back from work 1am... when I read this I already saw how much a fool I am lol. But I want others opinion
