Advice Anyone??

The guy that I like is cousin to my best friend. My best friend will invite me over when there is a family event so that I can see this guy, and I love to go, it is just that I feel as if I am imposing on the family sometimes. My best friend’s mom invited me to the baptism of the brother of the guy I like, and to the party afterward. I really want to go, but I feel like I am imposing again. I have told my best friend about this, and she assures me that the whole family loves me, and so has her mom, but I still feel the way I do. The other thing that holds me back, is the fact that this guy I like and I have been fighting lately because he thinks I am mad at him, and I'm not, but he won't listen to me at all, so I feel that is another reason I shouldn't go. I really want to talk to him about this in person though. Plus, the party after the baptism is at the guy’s house. I am just very confused, if anyone can help me, it will be greatly appreciated.
