Is it normal to feel sad and jealous when my boyfriend goes out without me?

I am a very outgoing person, however, I really don't have friends. 'girls night' is NEVER an option for me. My BF (27) and I(23) only spend weekends together due to work. My BF & I got an invite from his best friend to hang out( I love his friends) I like to plan things, they don't. My BF & I talked about it & I told him that I wasn't down to go (I live 45 mins away) but I said I'll go if he wants to. I'm not that GF that ruins fun. He said he'd nap & call me later. They said they'd go around 9-10(11pm) to a karaoke bar. BF didn't wake till 10. He called me & said he'd see 'what's up' w/ them & said sleepily he may not go. I said its too late for me but let me know what you decide. 10mins pass he calls laughing saying they are barely leaving and he'll go. I said have fun be safe..all that. He kept asking if I'm OK w/ it. My only hang up is the girls going they're taken but idc. I told him to stop asking because he's trying to make something out of it and I don't want to argue. He said ok he didn't want me upset with him and he'd text me all night and I told he didn't have to. This isn't the first time he's done this and no matter how many times I tell myself to chill, inside I get so sad and hurt and all in my feelings. I told him Im going to bed but I'm so upset. I feel like a loner and then I feel even worse because I don't know why I truly feel this way.
I want to know, am I overreacting? How should I handle this? I am sorry this is a mini novel, I just feel hella down.
