Movie name?

Hi all, I watched one movie 6 years ago and I want to watch it again but the problem is I forgot the name , I don't remember much but basically the story line is this:there's a man who live in a trailer and he went to a wedding and he was hitting on the bride,also I remember the bride was a hiking coach or something like that, and her husband I think was named cam or something like that and he played golf, or at least there was one scene with golf .bad explanation but that's all what I remember,thanks in advance
