I get it and know how hard it is. Almost 2 years ago at this point I came home to an empty house and it really really sucked... Def one of the low points in my life after a 7 year relationship. Hunting and fishing are what did it with out a doubt. It was fine when I was doing it but her brother and father got involved and then her Mom started complaining which rubbed off on her.
My advice is: Find the right girl! I did the whole online dating thing (yes it was weird) but it paid off in spades. Met someone basically from my home town and she fishes with me one day a weekend for the most part and has been to the duck blind a few times as well. When you find the right one it won't be a problem.
