Lost in the Roleplay

I'm a Daddy in my 50s who found solace and excitement in DDLG relationships. Last night, I was playing with my little one when something unexpected happened. She pushed me to boundaries I never thought possible, emotional ones that made me question everything about myself. It felt like more than play; it seemed real, raw, almost too intimate for the role we'd agreed on. Am I losing sight of what's appropriate? Is this a sign of deeper issues I need to address? How do others handle these moments without compromising their boundaries and comfort zones?
