I think one of her big problems was she was relying on Tinder and Bumble to find a lasting relationship. Both services are more focused or aligned with the hook-up culture and not with the idea of a long-term, stable, committed relationship.
She mentioned she grew up as a conservative. It seemed she would have been better served looking on sites like conservativematch.com, christianmingle.com, eHarmony.com or other similar sites which have a bias toward building and establishing strong relationships and not just hookups.
At the end of the article she complains so many of her exes sent her a congratulations message. I really don’t think she had trouble finding boyfriends. She just had trouble making them want to commit to her. She was either bad at choosing guys who wanted to marry or she has some issues that drove them away. But from my read, she had opportunities, yes plural, she just couldn’t get one of these guys to put a ring on it.
