Hey ITH. Wow. I don't know how other people are going to perceive this but if you are saying that the letter expressed your anger instead of you apologizing and telling him how to feel then personally I agree and think that this is good!!
You have been apologizing to him about his feeling the whole time and I think expressing anger might be a 180 for you. And judging from todays actions a good 180. Go to your friends for a few days and have minimal contact, let him miss you a bit. Even from IM and emails. Put up an away message you are super busy from taking a day off yesterday!!
I am glad that he did suggest the weekend to go do things as I know you have been wanting to something outside of the house. I believe that will cause an atmosphere where there is less tension and you can just enjoy each other.
