Is it normal that my bf never shows sadness whenever we say goodbye after each visit?

I had a great visit and enjoyed every second of the 8 days I had. When I was leaving I couldn’t help but to cry, I ALWAYS cry. I cried really hard this time more than other times. What always bothers me is that my boyfriend never shows sadness when I leave. It doesn’t seem to phase him! I’m the one sad and he isn’t. Last time I visited him, he was really sad and that was like the only time. This time he had a friend with him and she took me to the airport because he didn’t have a car. He was being a jokester as he always is with his friends, laughing, and talking as if I wasn’t leaving. We hugged n kissed goodbye and I left crying. When he got back in the car I saw him talking happily as if me leaving never hurted him.

Shouldn’t he be sad? I don’t know if it’s the same for guys. I kind of feel like if he didn’t have a friend with him he would’ve spent all his attention on me…I know he wanted me to stay longer and tried convincing me to…but I just wanna know I’m going to be missed as much as I’m going to miss him!
