It doesn't really matter that he didn't fall in love with you cos ...he didn't ... All that matters is that someday you're going start demanding from other people what you deserve and be willing to "completely" walk away if what you require isn't being provided. Cos I said so.
I dated a guy for a year I loved him but didnt tell him until we were over & at nc He started going to parties & started to not want to fix things between us we dont speak he still hangs out w my sis every wekend How did he never fall in love with me?
Because you weren't meant to be. Move on.
You obviously lacked a very critical level of intimacy .. Given your claim that you never told him you loved him .. That speaks loudly about the dynamics of your relationship.
I think the maximum that you can get this habit, not love.
