It's really great when you feel like you're with a guy who thinks you're, like, the best ever and is super-attentive and loves spending a ton of time with you. But there's a difference between a caring boyfriend, and a guy who's actually jealous and controlling. There are some telltale markers of trouble, and if you spot enough of them, bail on that relationship — it isn't going anywhere good. He fondly calls you crazy or too much, like he's so chill and you aren't. And that's bad, because it puts him a few rungs above you on the humanity ladder. Very uncool. When he smiles and says things like, You're perfect, like you're his personal Barbie doll. What's wrong with this, right?
