I'm not sure I bring anything meaningful to the table in a potential relationship

As great a person as I am (there doesn't seem to be a way to say that without sounding like a narcissist), but I'm not sure that I offer all that much to a prospective partner. I'm supportive and caring, but that seems like something which people* expect and consider a baseline rather than something worth considering. But then so many seem to get through without that so who tf even knows.

*I'm referring to women because that's who I'm attracted to, but I imagine men are similar.
