If you had to choose between blowing up or asking her to just listen to what your heart is holding, which would the better choice to you?

You can tell her. It might be counter productive, and it might not be. If you've figured out what emotional needs and concerns she has had, you should know if she wants more or less disclosure from you. If she wants you to open up to her more, then one dialogue won't hurt that much. If you do it though, practise it and make sure it isn't negative, angry, or threatening. You might get backlash...that is the chance you take. It might also help. Who knows? Every woman is unique as is every man.
