Girls, Girls is this disrespectful?

My guy friend was hanging out with a girl daily for about 3 months not really as a couple just good friends. Turns out she was talking to another guy in line at the same time. Long story short the she flew up to see the guy she met on line and they ended up getting enguaged. When she returned she started to call my friend again who didn't answer her text. She eventually called him and spoke to him telling him she is sorry for what she did to him. She wants to still be friends with my fiend. Would that be distespectful to her fiance since she is enguaged? Is it alright to have guy friends when your enguaged? Thank you for reading. I will be happy to answer your questions just send them to me.
