Thoughts on Regina being able to TLK Henry in season 1. Not to say that Emma didn't have the right-to be honest I'm still eh about that, but eh. I think she could have- she wouldn't have believed she could have, but I think she could. You don't just turn feelings off, and she loves him sooooo much, and before he got the book he must have loved her to.
I think she didn’t believe in herself enough to try. She was afraid of failure because she didn’t think he loved her and that failure would have destroyed her.
Remember she’d tried to True Love Kiss before and had it fail (not that it could have worked but the psychology is there).
