bf problem

So Me and my boyfriend have been seeing each other since March. It's a long diatance relationship. We live about 2 1/2 hours apart. And I have been the one doing all the traveling since we started seeing each other. He usually pays for everything while I'm there as far as food and stuff like that but he has only put gas in my truck one time. And we've had our ups and downs. But I also know that he holds my heart. Recently he has talked about wanting to rodeo full-time and then he also mentioned something about joining the army. So of course my first reaction is to kind of freak out when he mentions army but at the same time I just want him to be happy so I'm fully supportive. Not to mention that every time he's asked I have driven up to see him and I don't ask for anything in return other than for him to try and come and see me but he can't afford to take off work and drive down here for a weekend. So of late I've been spending some time with a friend of mine who likes to challenge me as far as what I'm going to do with my life and comparing where I wanted to be at this time in my life to where I am at in my life right now and it's kind of opened my eyes. Is it wrong of me to stop living and basing my decisions off of my relationship with my boyfriend and just live for myself and experience things on my own???
