I purposefully look sexy around his friends and coworkers...
Whenever I know that his friends or coworkers will be anywhere near us, I purposefully dress up, do my hair and makeup and tweak my appearance specifically to look as sexy but not trying too hard as possible. I want him to get props for having a hot girlfriend and make his buddies jealous of him. Whenever they are around, I act as close to "perfect girlfriend" toward him as I possibly can so they'll be jealous of him.
Whenever I get the opportunity, I do my best to make great conversation with those guys and will regularly cut them off mid-sentence to love on him in front of them. I'll take every chance I get to say something about him to make him look good - I'm not gonna lie, sometimes I embellish or make shit up. I won't go out of my way to do any of this but when I get the chance, I sure as hell do. That said, I keep a distance from his guys who have girlfriends and just talk to their girlfriends instead.
I don't tell him this and he has never questioned it because I try to be subtle about it. Is it normal that I try to make his friends jealous of his girlfriend?
