That is not how to set a boundary and the e-mail seems like a long laundry list of "wrong doings" on the part of your H.
You said your DB Coach suggest you focus on positives yet you want to send him a message that points out negatives.
You cannot control one's facial expressions (your H frowning at you).
If your H speaks to you in a rude/harsh tone of voice let him know WHEN IT IS HAPPENING in a calm way. Same with the problem of his comments while you are on the phone or his complaints about money.
