How can I encourage my boyfriend to be more active? Or let me be active alone?

My boyfriend and I have been together for a little over half a year now. We live about 45 minutes away from eachother so he only visits on the weekends. When I met him, he described himself as being a very active, outdoorsy type of guy. I’ve always been very active and want to experience more of the world (traveling, hiking, camping, cultural events, etc.). It’s like pulling teeth trying to get him to participate in activities with me, but when I try to go alone, he gets upset with me, claiming “Well, it sure looks like you really want to spend time with me..when you’re walking out the door.” I want to spend time with him but I am not happy watching television indoors all day every day of the weekend. I have a quiet day job and want to get out and explore on the weekends. He’s a really sweet guy but it seems that watching tv, cooking, and video gaming are his only passions as of late. How can I encourage him to be more active like the person he was when I met him? I’ve sat him down and told him all of this, and his response was “We have to compromise.” Last weekend, I watched a total of 12 hours of Battlestar Galactica with him because that’s what he wanted to do. I asked that he go on a 2 mile walk with me, and he did….after complaining for 30 minutes and being in a bad mood throughout the walk. Maybe I am approaching the situation the wrong way….. any help would be appreciated.
