Smoke From A Distant Fire

I am happily married with a son. Years ago, however, I had an incredible affair with the woman who I still consider the love of my life. There was never an official breakup, but we separated "temporarily" and that became permanent., though neither of us expected that. Years went by and she moved and I moved...That was 1974, mind you.
A month ago, her father died. I saw the obituary and wanted to go to the wake, but couldn't because I had to go to my neice's wedding in Maine. I didn't think she cared. She called me at work a few days after the funeral and left a voicemail message, saying that her mother wondered where I was. She asked me to call her mother to express my consoldences. I did that, though it seemed an odd request. Then, she called again and got me. She began to ask me to call her mother again, and I told her I did. She suddenly switched tones and we had a one-hour, happy talk.
Now all this has me off the rails. I need some perspective.
