How to deal with frenemies
Confide in a true friend that you trust.
If you're not sure whether or not this person is a frenemy, talk over your concerns with a friend you're absolutely sure about and happy around. This person may throw new perspective onto the situation that helps you to realize the value of your relationship with the frenemy.
Be certain who you're talking to won't pass your concerns back to the frenemy. Play it safe by ending the relationship gently.
