Single mom in a relationship

My life’s pretty hectic, I’m always running around with limited time on my hands. I’m a single mom whose the sole provider of my child, I work full time plus more and the little time I have is usually spent with my daughter. I’ve been dating someone but it’s been consistently after 7pm (when my daughters asleep) and sometime I leave around 11pm or get up bright and early and bolt home for my daughter, I feel like our relationship will never move forward going at this rate, right now it’s sex and cuddles then I’m gone. How do I manage building a relationship with someone and being there for daughter, working full time and all the other running around I usually have to do? Is it always going to be this hard?

I can’t help but feel guilty if I’m not there for her whenever I don’t have to be gone (work, groceries shopping I do alone because of covid, ect) I love my baby and I’d never put anyone over her but I can’t help but day dream over being in love and having someone around again. It gets lonely sometimes.
