Ugh. Last year, my daughter was 17, first boyfriend, they were Prom King and Queen. Then, about a month later, he dumped her. I think she cried for about 10 days. Went through at least five boxes of tissue. Nothing I said helped, so I just said "I love you and if you want to talk, I'm here." Then I hugged her and she grabbed on to me and wouldn't let go for a good 20 minutes. My shoulder got really wet and smudged with mascara. She eventually came to me and wanted to unload, but it took a week or so.
It's so hard when our kids are hurting and there's nothing we can do about it.
