So the friend whom I asked to join me for the ballet would have been interested but she has already committed to a play in San Francisco on that day. So I need to keep looking. And here I have a question.

In 2011, I worked together with a woman. She was an office manager at my work. We were then both laid off as part of a massive layoff. Several years later, for a few years, we were casual acquaintances. We went for walks together and she invited me to her house where I met her daughter and eventually the daughter's new husband. At some point she and her daughter and I went out. It was probably slightly less than 10 years ago. She is several years older than me and probably in her late 50s now. She shared a lot about her life with me.

Then she disappeared and stopped responding to birthday wishes over email. I was still subscribed to her updates on Facebook and occasionally liked them but eventually unsubscribed because she shared sciency stuff and that is not my area of interest. I never unfriended her, mind you, I just unfollowed her.

Suddenly, several days ago, I saw that she liked my post with a picture of my adult son. I then messaged her, saying hello. I see that she saw the message but she has not responded. I also finally see the history of messaging between her and me. I did not pay attention before but now I see that in 2018 we exchanged messages, planned to get together, she was very eager, but ultimately she disappeared, which happens to people when they get busy and it is completely OK with me. And she was not checking messenger at that time. But now I see by her little profile thumbnail that she saw me "hello" message. Still, since she has not written back, I decided not to say anything more.

Today, though, I see that she has just now liked another post of mine with a photo of my son and his GF. So she is actively liking my posts but is not responding on messenger. Weird, no?

I have her phone number. I wonder if I should phone her and offer to go to the ballet together. It would be a nice opportunity to reconnect after not seeing one another for more than 5 years. But at the same time I do not want to put her on the spot and create an uncomfortable situation if for some odd reason that I am completely unaware of she does not want to communicate with me.

Note that it is not that she has been liking my posts all along. In fact, I think this is the first time in years that she did. It was sudden.

For context, she is an extremely nice and warm woman. As an office manager, she was simply extraordinaire. She always went above and beyond.

ETA Maybe I should text her, not call her. This way she would have an opportunity to ignore my text if she feels so inclined.
