<human>: Give me a shortened version of the text

So my best friend text me today and said she really needs me. Her and her fiancé broke up. My boyfriend [25F], myself and they were all really close friends and have been for the last 5 or so years. 

Backstory: the fiancé [23m] joined the army abroad where he's from and my best friend stayed home here in Ireland as they're not yet married and not permitted to live together on base. So for the last 4 years they've had a long distance relationship. It's been hard on her and she's told me she's depressed over it because she's missing him so much. He said it's just not working anymore. They only see each other 3-4 times a year. 

I have had a rough patch recently with my own boyfriend and we almost broke up, but decided to stay together and we're happier than ever. We're going to go visit her this weekend, but not sure what way to act, why to say/not to say? 

Help please!
<bot>: my best friend and her fiancé broke up and she's turning to me for advice. I don't know what to say or how to act around her.*
