My family is small and simple. I started playing a long, long time ago with some Sim I had created myself. Then I spotted Don Lothario for the first time at Chez Llama where he was the chef. From then on, I had to try and play as him, and as it turned out I could never let him go again.
Then vampires were released. Don met Caleb. They became fast friends. Caleb was suddenly everywhere that Don was, all the time. I then started new saves with Don just trying new things and stuff. Caleb became an outright stalker. So I caved at some point. I don't recall if romance between them developed autonomously or if I ended up giving it a small push. But I remember that no matter what new save I started playing as Don, Caleb would be at his door constantly and stalk him wherever he went posing as a vendor, a bartender, or a street musician. You name it. If Don happened to be in a relationship with someone else, Caleb would continue to show up all pouty-faced making me feel bad.
If they want to be together that badly and continuously across saves, then sure. Why not? It's sweet. They have been a couple in my games from about a week after the release of Vampires.
