Do I have a right to be mad

I just had my baby shower on Saturday. Almost all of my boyfriends friends showed up with no gift. That wasn't a big deal but the part that bothered me was that I always bring gifts when their girlfriends have baby showers, and he also always buys their kids expensive birthday gifts. He actually took one of their daughters shopping for her birthday last month and spent about 200$ on her. Do I have a right to be mad that none of them got my baby a gift
