Wife pissed about surfing.

Problem, My wife doesn't like my riding partner. I have the most difficult time getting anybody to go out in the boat with me ( why I have no idea). This friend will go almost 90% of the time. Most of the time we have to ride with only the two of us. If he doesn't go I can't go, because my wife wont pull me with out a third. All I want to do is go out and have fun and ride a few sessions. Why does she have to be such a #*$!* about it. If I go without her she also gets mad, so either way she is not happy. She thinks it is not relaxing going out and watching us surf and fill ballast bags. This is totally frustrating me. Kinda ruins my good time. I am almost to the point of saying #$%@ it ! and sell the darn boat. I swore I would never be boatless again. Any suggestions to make her chill? And yes I have already tried to get her into surfing, and that didn't work. Should I ignore her attitude and just go out, or obey her wishes and not take my only friend that surfs, out with me ?
