Why do ex partners from your past show up in your present, seeking to reconnect with you?

This man has been married since 2014, and it always appears to be a competition with his wife. I know a woman who got involved with him out of spite and ended up having an abortion. She has children with other men but essentially tried to imitate his wife. She even bought a white dress like his wife wore. Years later, she now wants to get back with him. She’s a known cheater. The man said that no one was interested in him respectfully until he got married, but for some reason, women believe they can compete with his wife. Additionally, this woman has caused the breakdown of other people's marriages.
