Is my boyfriend jealous or what?

We work together and I study different thing

I have online classes and worked half Friday to go to his house to study

Once he got angry and starteda saying "you are using me for study"... uhm.. it was mutual agreement that ill study at his house at even more, it was HIS idea because i live faraway while he lives infront of our office

Then he goes:"you leave again? ok then... i dont get why you have this behaviour, wtf you think you are."

Umm... what in the fuck

What is his problem... suddenly he doesn't like me studying
