What if i dont find romantic love

I've been thinking lately a lot about how ill handle being in love. I mean I like to think that if I ever date itll be to marry yknow. I want something homely. The problem is that I can never fully be in love, any love that I feel immediately turns into admiration upon more delving into it. I can never say that im fully in love, it always circles back to platonic. I know I'm capable of it, I dream of deep affection, the type that gets you married but it doesnt work. 

Causing my own loneliness because I cant rationalize my feelings.
