<human>: Provide a brief overview of the text.

I want to preface this post by saying that I do not have very much relationship experience, so I really have no clue what to do or how I should feel about any of this. My boyfriend [25] and I [25] have been together for about three years now. We've hit a few bumps along the way, but for the most part we've been happy. In the past few months, I've felt like our relationship has hit something of a standstill. I'm not unhappy per se, but there isn't really much passion. He is sweet and affectionate in his own way. I still enjoy spending time together and the sex is good, but I feel like we're not going anywhere. We both agree that we're not interested in marriage any time soon (right now we're focused on excelling in our jobs), but I think it's a direction we should be moving toward, while it isn't something that's crossed his mind. 

I guess at this point I just wonder if we are even compatible in the long-term. I enjoy hiking and going out to bars with friends, but he's not too outdoorsy and he's not much of a drinker, bar person, or night owl. We both have similar senses of humor, taste in movies and video games, but I wonder if that is enough? 

Then sometimes, I go out with my girlfriends, and I miss being single, and flirting, and dating different people. Which makes me wonder if I am even mature enough to be in this relationship right now. I don't want to just throw away a three year relationship and friendship.

So, I guess what I'm asking is, how can you tell when a relationship is no longer worth pursuing if there is no major catastrophic event (like cheating)? And if my relationship is worth pursuing (which I realize is something only I/we can decide), what can we do to make things better?
