I think a little faith is not uncalled for in this case. I don't see you as someone who places her trust and feelings in someone who does not deserve both.
It's not stupid at all. That was incredibly brave of you, Yang. It would indeed have been unfair for you to have continued in a relationship once your heart was not in it, but it takes an incredibly strong person to be able to do so. Especially when the future with the one you truly love is unknown.
Feelings are part of what makes us human. The bad, and the good. As much as we wish we could turn that off, learning to overcome that which overwhelms us can also push us forward, one step at a time.
