She had been sitting outside the building looking in for the whole evening. She desperately wished she could've gone in- your own parents' wedding was something you wouldn't want to miss given the opportunity. But she barely held it together earlier when she had given her father her empty diary.
"Give it to Amy if she starts acting strange," she had said carefully. The tears, she could feel them coming. Giving her father a choked goodbye, she had darted to the curb in the parking lot. Her husband was seemingly dead, again, and she couldn't seek the comfort of her parents because not only did they not know her, but she didn't even exist yet. Not really for them anyway. She technically existed as Melody, within her parents and the Time Vortex, and as an anomaly the universe didn't know what to do with. Rather depressing, which didn't help the tears rolling down her cheeks. She scoffed as she wiped them away. Tough old River Song, wife of the Oncoming Storm and arguable psychopath, did not cry. Vulnerable emotions were attempted to be shoved from her mind by the Silence. It wasn't until she fell in love with a madman that these dreadfully human things had begun happening.

He would come back. One of the benefits of having your past be someone else's future- they weren't really gone until you forgot them. There was no way she could ever forget the raggedy madman with the blue box.
