I'm 18, Single and Stuck

In my opinion, being single isn't as bad as it seems. No commitments. No hassles. No problems right? Wrong. Even being single cant be stressful. My list of women of "friends" has gone from 4 to 1 pretty much. Me and her.....we're together....Kinda. But we're not really together but when we are together we act like we're together. You get all that? Good. I turned 18 yesterday and my relationships with the people around me haven't changed much. I'm still the same old me. Just as calm as I always was. As far as LOVE goes, I'm still getting around the concept of it. I know a few people who are already engulfed in it and they seem happy with it. I'm still tryna figure out what my next move is, but in the LOVE aspect, I hope its a good 1.
