Is my Sister Actually Cheating on Her Hubby when-----Indulging In This?

***She Met an Old Friend From The Past on FB and Now They have Resorted to Their Phones For Text and Calls But yet She Has Told Her Hubby of their Friendship. He is Okay with it. She appears Very Into Him with All her "Excitement" But Claims JUST FRIENDS. I Feel it's Inappropriate when Married. Any Thoughts? xxoo
