My boyfriend gets upset when I talk on the phone?

I’m always at my boyfriends house and he was upset recently that I was on the phone with my cousin (she’s my best friend). I had stayed at his house for about a hour waiting to go to class, but when I noticed he was upset and I confronted him about it, he told me it’s because he didn’t get to spend time with me and actually hold me. He claimed he wanted “atleast 10 minutes of my time.” but the thing is, we just got back from vacation so I was with him for a week straight; and for the past 6 months we’ve been together, he’s the only person I hang out with. Am I in the wrong, or is he? Please help!
