Is it normal to be jealous of my boyfriend?😕

Brianna
Sometimes I get mad at my boyfriend when I want to talk to him, but he doesn't have the time because he's either working, or hanging out with his family or friends. When he hangs out with his family or friends, I know I shouldn't get mad, but I do. At first it seems like I get mad because he doesn't have the time for me at that moment, but I'm starting to realize that it might be more of a jealousy towards him. I'm in my 2nd year of college and I have been having trouble making friends (at the moment I have "friends" and it's never been easy for me to make friends). He knows this. I kind of rely on him and want to talk to him constantly because of my current situation, so when he's not able to for various reasons, I get upset. I want to be able to tell him when I'M hanging out with my friends. Don't get me wrong, I love my alone time, but I start freaking out when I have too much of it. He was supposed to visit me the weekend of the 15th, but realized he couldn't because he had made plans with his friends prior to this. He offered to come next weekend, but I said no due to my feelings. So, my overall questions are: does anyone get jealous of their boyfriend? How should I deal with this? Should I talk about this to him?
