If someone is 62 and never married, here are a few possible reasons:
- She's gay, either openly or closeted.
- She's bi.
- She's asexual.
- She had a lost love and doesn't want anyone else, even though that person is gone.
- She likes being on her own and doesn't want to share her house, her credit rating, her health issues, etc. with another person of any gender.
Only #4 is remotely close to her being interested in someone like you. You overdid it, and you blew it. Frankly, I would hang up on you, too. You sound clingy, needy, and insensitive to other people's feelings or interests.
Let.It.Go.
