Feeling like love can only come very late; weird?

I'm 32. I've only recently felt anything that might be love. I also, as regards having kids and wife etc, feel under the shadow of my sister and her partner and kids, and my parents. I am the baby of the family, somehow not made for stuff like that. I feel like I may not find true identity or love until even my parents are gone. I don't, of course want them to be, but it might be a long while til I feel like my own identity is defined enough, even then with kids it seems like whats the point with my niece and nephew and sister invetiably 'being more mature' or doing it right. I contradict myself slightly because I have had a thing recently, that felt like love, still dunno if want to be raising kids, in the position to do it under the shadow of those more responsible.

Are these feelings normal, especially for a youngest, to be roaming for a long long while? No ability to find love or something meaningful or even wanting to? Or am I weird?
