Have you ever had a friend that's never available, cancels etc. Or basically just doesn't initiate stuff, then as soon as they become single they want to meet up all the time?
It happened to me with someone I don't stay in touch with anymore, i had invited her to a party 4 months prior, she declined and then didn't hear a word for 4 months.
Then she got in touch out of the blue asking if I wanted to meet up, and told me she was newly single.
I met up with her and then that week she literally wanted to meet nearly every day. It was too much for me both socially and financially so I said I couldn't.
But it was just that, going from nothing in months to full on, wanting to meet daily.
Then it tailed off again.. i just felt like she was using me a bit as she had never been that interested until she was single.
