I agree with OwnIt, do not read her the letter. Don't think this will be your last opportunity to let her know (even though she knows I understand your desire), this is a long process and there will be many opportunities.. And if you really want to do it for yourself, then it will be much more meaningful if you do it at a time that you are not expecting her to react in a way that reunites you two.. Right now, you want her to hear it because in some way, you think her eyes will open and she will remember how much she loves you and wants to be with you forever.
