(This applies to e and g)
He didn't like how you had a lot of very close guy friends. He hated when you smelt like their cologne or he saw some of their clothes in your closet. He always gets really protective of you. And whenever they're around he makes sure you are wearing something of his or smell like him or wear something pretty he got you. He hates when he sees a pic on social media of one of them touching you or something, he instantly sends you a bunch of cute texts about how beautiful you are and how much he loves you, hoping that one of the guys will see the texts, just a reminder of who is your boyfriend.
