Why are females so freaking difficult to be friends with

Is she into your husband or trying to destroy your happiness with your man?

she sounds untrustworthy

My mom's like the only female best friend I have now and she relates this girl to an old friend of hers who's tried ruining my parents marriage by going after my dad and getting him alone. But why would females throw away old friendships over their friend's husband of all people?
