I fundamentally disagree with the whole cheating thing, on the grounds two of your girls are cheating on their spouses. This is one big NTR conga line, so it holds very little weight to my morals since basically everyone is doing it now. Hell, I wouldn't mind coming to see some of my girls have basically snagged up some girl off the street. As long as they're not bringing in other men, I don't have to beat said men with a bat.
Besides, most of the time it seems the moment you use Awaken, they've been harem'd. Lilly is pretty laid back about the whole thing, but she is in fact your girl at that point. Once you zap someone with your powers, they're kinda screwed, as even doing the bare minimum seems to make them want you even if you barely talk to them. I'm sure even though Emma had the briefest scene of the bunch, she's gonna start coming around.
TL;DR it's hard for me to feel bad when my girls are cheaters too.
