is it normal to not want a relationship?

I’m 21, so I have my whole life to find a partner but I’m starting to feel like I don’t want to be w anybody. I just want my life to be me and my daughter (she’s 1) growing up together and exploring the world. I want to spend my time working and making the best life possible for her and I can’t even think about being w somebody. I just broke up w a boyfriend simply bc i don’t want to be w him even though he is great. I just like having my own space and my own time, i like to work and have the money to afford my own things and take care of my daughter on my own. Other than that every relationship i’ve been in it felt like it was adding more stress to my life than anything. relationships make me feel insecure and crazy. they completely make me lose my sense of self and feel bad about myself. maybe it’s not relationships in general and it just the guys i’m picking but idk. bottom line is i hate being in relationships. i hate having to wait on somebody and clear things w somebody before i do them. is this normal or am i gonna grow old and lonely 😂
