Yeah, I'm single.
At times, I just feel "this sucks", other times I feel grateful, as I feel I get so much freedom, as much as it can be a bit painful knowing so many friends who are getting into relationships/getting engaged.
The thought of dating makes me nervous - so much political correctness regarding "who pays?" that I'd be worried about offending the woman who I was dating, or committing some awful faux pas.
So yes, it can be difficult, but I get through.
