Friends again

Twenty-one years ago, I had a best friend, she and I did a lot of things together, joined a little theatre group, took photography courses, you name it we did it and had some wonderful times. We even vacationed together with her husband and mine.
However, everything wasn't as happy in her house as it was in mine and, I won't bore you with the details, her life changed directions, she did things that I did not agree with, but it was her life, and as a result we lost contact with each other, I missed her terribly.
When my husband died she read the "obit" in the newspaper and recently called me. She lives in a city near me, has remarried and settled down.
"Would you like to have a cup of tea" she asked. At the time I was not ready, so she told me, if and when I was, give her a call. Some time later I made the call and this past Tuesday, we met again after twenty-one years.
She told me she was so nervous, she was ready hours before we were to meet. We haven't changed, well, I have a few more grey hairs, hers are there also but covered up with the assistance of "Nice'n Easy" we both have a couple of extra wrinkles, oops !! laugh lines, she has some extra pounds added to her frame and my eyes require the help of some glasses.
We went out for lunch and five hours later we were still talking and we still have a lot of years to catch up on.
We are going to get together again.
She was my one and only best friend years ago, so when she left my life back then, I was hurt, angry and upset for a long time. At this point in time I have many friends, I am going to include her as a friend, but not a "best and only " friend, as I don't want to be hurt again.
