tired of being the one who holds it together

so i work nights at this diner and my little is a bartender during the day. we do this daddylit thing, you know? like im her daddy and shes supposed to be looking up to me or something. its been going on for a while but lately she's been acting all tired out and distant. i try to give her space but i feel like it shouldnt fall apart so easy right? ive always thought of myself as this strong dad figure in her life, even if it is just playacting. so last night we were closing up shop late and she was supposed to be doing some paperwork for a big order coming in tomorrow. shes been slacking on work stuff lately too but i try not to get mad cause i know shell come around. anyway shed barely touched the papers and id had enough of playing nice so i kinda snapped at her, told her to focus on being responsible and stop acting like she wasnt an adult. it felt good to let loose for a second but when she looked up at me with those sad eyes? man it broke my heart right there. we sat there in silence after that till we were done closing, neither of us talking about the tension hanging between us. i went home early cause shes got work tomorrow and id had enough. sitting alone in my apartment now just wondering if its me or her or both who need to change. feels like a good thing shouldnt end this way but relationships dont always work out no matter how much you try. guess im the asshole for yelling? guess shell find someone else better than me who can handle being a daddy figure? not sure what else to do except keep my head down and hope shed come around if i give her space.
