Are you happy being single?

Not entirely, but I'm patient..

Not really, but I've learned how to make the most of it

yep - very happy in singledom..

Not really. But I'm content and stable. Relationships are more trouble than they're worth. There are downsides to being single; but, imo, they're less problematic than relationship downsides. Rollercoaster vs ....driving a car, I guess. Sure, you don't get the ups, but you also avoid the downs.

No

I'm not happy but I don't want a relationship right now. I'm not interested and I don't want others to deal with my problems.

Unfortunately, I can't see myself being any happier than this. So... I guess so

I am not happy but I don't think it has much to do with my single status

NO, I am married :P
