A HIMYM fan in reddit:
Yes there’s a whole episode about her wanting to tell him she loves him, but I don’t think it was true love.
I always felt like she learned to love him because he was good for her, but not for being Ted.
Honestly I feel the same way about her relationship with Kevin, both ted and Kevin put her on a pedestal,
loved her and would do anything for her, that made her feel like she should be with them and they were the best for her.
She even say at some point that she SHOULD be with Ted, it would be EASIER to be with him.
When I first watched the show I started feeling this way after seeing how she loved
barney, it was just different,
but when I rewatched I was sure.
