Neglected..?

Okay so it has been bugging me for a long time how neglected I feel by my boyfriend. We have been together a year and the longer we date the less we connect. Don't get me wrong, I am going to marry that boy- but he has been a very "him first" kinda guy recently 
Also recently, one of my guy friends and old flings and I started hanging out with a few of our friends. I have always gotten along better with guys than girls since I was raised with my brothers. My boyfriend started getting defensive, he knew that I cut off my guy friends to commit to him because I accidentally flirt a lot with guys. I am usually honest to god joking but they and my boyfriend see it differently. 
Is it bad that I kind of liked how my boyfriend got jealous? It made me feel kind of important again.
