Please don't give h that letter. I don't see how it will get you to where you want to be.
Instead why not start taking care of you. If you are tired of conversations with h always being one sided then stop talking...he'll either fill in the silence and surprise you or wont. If you're tired of hearing him chatting away with friends and not you..well then get on the phone and start chatting and laughing with some of your friends. If you're tired of him choosing his friends over you...stop making yourself so available and stop waiting for him to have time..instead make some plans of your own with your friends and let him wonder.
These actions may wake him up into realizing that you aren't always going to be sitting around waiting for him to make time for you and they may not...either way you will no longer be sitting around waiting for him to make you happy you will already be.
