Do you think this is rude?

My boyfriend always answers his phone no matter what we’re doing. It’s usually always his best guy friend who calls. They talk to each other at least twice a day on the phone and see each other very often. Their phone calls can last a hour or more.

We don’t really get that much time together we work opposite schedules. When we get a chance to watch a show together, or just sit and talk, so many times he’ll get a call from his friend and talk with him and I’ll pause the show and wait for him foreverrr. I’ll give him a look so he knows I don’t appreciate that (and I have mentioned it to him before) but he will never ignore a call or make it short.

I’m glad he has a good friend but I think it’s rude to answer every single time and talk for freaking ever when we are in the middle of something, what do you think?
