I like being single, a lot better than I'd like being with the wrong person. But it's also a challenge knowing there is a 'right' person (not perfect, but right for me) out there and not knowing them or having them in my life that way yet.
I see some saying being single is good because of certain freedoms but honestly, to me, a healthy relationship involves giving each other some elbow room too, so that freedom thing may not be that big an issue.
It comes down to what you find more beneficial. MORE freedom or having someone there.
