Is this abnormal/wrong?

My boyfriend of 5 years has been spending a lot of time with his new friend lately, and I feel really jealous. He always tells me about what a great time they had, the cool things they did, etc. I’m a college student and I have to wake up very early during the weekdays so when my boyfriend and I hang out I’m usually really tired and we just hang out at his place and end up falling asleep. I’m happy he is having fun and making a new friend but for some reason I feel really jealous and sad.
