I think that Glory is bi and as a dragonet, she had a crush on each of her friends at some point, the longest crushes lasting around a year for Clay and Tsunami, the shortest one lasting a few days when she had a crush on Starflight.  She still had lingering feelings for Tsunami a little before they escaped from the mountain, but that faded fairly quickly.

Glory wouldn't like having an actual date and would rather just hang out informally.  She would probably end up going on a walk before cuddling up on a couch with her loved one.

Glory as a parent would believe in letting her kids grow up and be their own dragon, so she'd let them make mistakes then teach them how to avoid making that mistake again.  She'd give them coins every now and then, but would mainly leave them to make their own money and learn how to finance.
