Smothering

Help. My bf is still smothering the shit out of me and I'm just mentally exhausted. I need alone time, he doesn't. Like ever. He wants to be with me all. Of. The. Time. I've had to put a rule in where he goes home twice a week so I can have space, and when he does, he has to FaceTime me to see me at least!  He's made me his entire world!  I'm at my wits end. And it's so sad too, bc he has so many other great qualities, but he's pretty much a girl. Which means I have to play the guy role. Has anyone ever had an SO that is completely dependent and had separation anxiety!?!
