What should I do?

Just be there for her if she needs to vent or just talk. You can also take her out and have fun. Do fun things to keep her mind busy and off of him. There is really no advice that anyone can give her to make it better. the only thing that will make it better is time.

Just by being there and listening to her would suffice to uplift her. A shoulder to cry on and an ear that would listen is the best thing you could do for her. Let her cry, it would be good to let it all out. And after that try including her in your activities. If the guy does not want her then she is better off not having him as a husband.

what a jerk!!!!! if were jessica i would take her out for a night of fun to get her mind off of it. YOu could bake her some goodies and watch a comedy with her. i suck at advise so you may not wanna listen me! lol. i know that i wouldnt bring it up or talk about unless she wanted to. there is really nothing to heal her broken heart but time i believe. i hate that too. just encourage her and dont let her be down. you only have one real best friend in life in my opinion so do what ever you think she would do for you if the tables were turned.
