Relationship life

Ive had a few long term relationships over the years but recently Ive found myself unsure about whether I want a relationship because of the level of commitment that comes with it. The thought of not being able to do what I want when I want without giving someone else a running commentary on my every move just feels exhausting to do and the level of time people seem to expect you to put into a relationship just feels like too much I like my space and the thought of seeing someone daily or most days in the week sounds like I dont have time for other things aswell I dont want to lose myself and who I am when Im in a relationship I want to keep my identity not lose it to become a part of someone else but I feel like that is expected of me since Ive confided in my mum because we are quite close she said that being in a relationship your supposed to see them lots and share your space with them but that just sounds suffocating to me I know I never plan on having children either which also tends to have people telling me I will change my mind even though I am an adult who doesnt want that responsibility because like romantic relationships I would lose my freedom if I had children and even if it sounds selfish its not something I want to give up is this really something I have to lose if I want a relationship?
