How do I help my friend after her breakup?

Well my best friend's boyfriend started ignoring her and then she got dump like just before christmas v-k by her on and off bf of about a year (which we later found out by HIS best friend it was because he wanted to'go further'and it was going nowhere). We're all 15.She tells me she's ok but I can still see it in her eyes.

its better if you just let time heal her wounds bc its sumthin she gotta deal with and grow from
