If you're going to lay it out on the line like that then dont' give her a way out. Don't say "I understand if you dont' feel the same way" Leave it open ended, see what she has to say for her self instead of just agreeing with you. Thats always an akward thing and hard to do, but if you express yourself honestly you should be fine.
this being said I do agree that a kiss would convey everything you're saying without a word, and can be less akward
