Some women get off on taking married men, even if they already have a long-term partner. Ex-friend of my husband did the same crap by chasing the married men in her friend group. The thought process is that of someone who derives their self-worth externally through others. It’s a hungry, endless void that is rarely satisfied. The thought process is something like, “Wow, he’s married but he’s throwing it away for me. I must be so amazing!”

If it works and the marriage ends, the married man loses his shine. To fall for her makes him unworthy. So he goes on the shelf while she seeks out other married men.
