If you were a bridesmaid and the bride to be was being an absolute bridezilla from hell would you forgive her?

One of my good friends (Lets call her Jan.) was the maid of honor for her best girlfriend's (Lets call her Tina) Wedding 2 weeks ago and she was being an awful bridezilla. Well anyway Jan felt insulted after she helped plan the rehearsal dinner and acted as the de-facto wedding planner and in her opinion she felt that Tina did on the day of the wedding was ***** and ***** about everything. (I was there and trust me she was being a bit of a cow!) Tina even insulted her personally all because she felt Jan's shoes didn’t match her dress. Well after the wedding Jan felt so angry at how she acted and behaved that she has been ignoring her phone calls. Tina feels awful for how she acted but is worried that her friendship with Jan that she greatly cherishes has been tarnished. What do you think would be a great way for the two to make amends?
