I've been single for ages. Although I rarely turn down an invite and I'm quite sociable, weekends are the time I'm least likely to be socialising. Even so the last two years haven't been lonely. I have a couple good girlfriends and most weeks I get to see them during the week. There's no law that says that socialising must be done at the weekend. It's only 48 hours.
Here's the question. If a friend you'd known for decades invited you because you are dating somebody, do you accept the invitation with relief, gratitude and excitement? or do you turn it down because you know in your heart you are still single, and you're baffled as to why you weren't invited as a single person. Might it be better not to get used to being included?
