Frustration!

Husband is nagging me to go to his brother's house for the weekend, 5 1/2 hours away. He has asked every weekend since the New Year! I have explained all the reasons I don't care to go and have offered that he is more than welcome to go by himself! And yet he persists! His brother is a nice guy, but when we got to his house a couple of things happen 1) His brother  announces that he is not there to entertain guests (sorry, but I think this is rude) 2) This is my husband's home town so he always ends up hooking up with old friends that I don't know well and they spend the day/evening reminiscing about people/events that I also don't know and can't relate to. I have been married to my husband for seven years and his "old" friends show little interest in getting to know me. If I try to join the conversation, I am usually ignored or get a "that's nice" before they turn the conversation back to their shared experiences. And to make matters worse, my husband was married to a local girl and even ten years after their divorce, they will still ask him about her with me sitting right there 3) We don't do anything while we are there, just sit around!! I can do this at home and not waste 11 hours of a two day weekend driving to just sit around bored to tears!
Tired of being nagged and bullied into doing something I don't enjoy. This is my husband's typical pattern, just keep pushing until I finally give in. It's exhausting!!
