How can I help my girlfriend ?

I been with my girlfriend for 2 months she just got out of a divorce which was hard. Also she lost her first husband 2 years ago she's had it rough. This other guy she married she wasn't happy with him even though she loved him he tried like hell to make her happy the marriage only lasted 4 months they were together 2 years. She has a son from her first marriage from her husband that died he just turned 10 he was only 8 when his dad died which was hard on him they were so close to each other. How can I help her feel better ? What should I say to her ?
