(I'm not going to lie, hearing her say, "He's everything you should have been" during our last meeting cut me to the bone.)
That is exactly why she said it of course.
I am like you, not very keen on social situations and do not enjoy meeting people for the first time. I have been more able to do it when I had W with me, but now I have to stand on my own two feet.
To that end, I decided I would take dancing classes. I enquired three weeks ago but have prevaricated and made excuses about why I couldn't do it. Well last night I went and it wasn't as bad as I expected. I got out of the car talking to myself, saying "I can do this" over and over. After the initial shock of walking in to a room full of strangers, I was taken in hand and actually enjoyed my time there. At the end of the session I was taken by surprise that the time had flown by so quickly.
I was informed that these classes always suffer from a shortage of men, something that my W has been concerned about, so that helps a bit maybe?
