His last girlfriend's parents were very nice. During the years they were living together, they invited me for Christmas and Easter dinners with their family. The girl's mother passed from cancer in 2011, a few days before my sister did of cancer as well. I went to see her mother at the hospital. She was comatose by then. She was a very sweet woman who I thought a lot of. His old girlfriend was there with her new boyfriend. She eventually married him, had a little girl, and they moved to Texas. I hope she is happy in the life she chose.
We’ve all had our hearts broken at some point. I had a girl crush me 30+ years ago. Your son sounds like he’s comfortable with himself and doesn’t need anyone else to “complete” him- believe me- that is a gift
