Well I personally do not know what it feels like to enter subspace so I can’t really advise on the coping strategies while in it. As the lead, you have a responsibility to know what too far is. You already know what too far is with her, so maybe not rely on her to tell you when she is gone. If she drops into subspace and loses her sensibility, that is kinda the point of going there in the first place. You need to know when to ease up. I’m sure the comments will do a better job that I will. Might want to ask a female blogger.
