Letter 1 of 5 from 1919

1 letter a day will be posted, for a total of 5 letters. The last will be the most interesting and leaves you hanging. The moment I began reading I began to note he was obsessive. As I transcribed all of them, before I got to the final letter I analysed enough to realise he had some issues (not that he's overly romantic, but that he may be controlling).
In effort to be as accurate as possible, I left in all his eternal grammar errors and spelling errors as well as note certain things in his writing so the reader will see without having to read the actual documents.
I believe him to be young (like my age, which is 19), and have identified three other people in his home.
Here is number one, transcribed for your pleasure:

[Grand Rapids, all one word, done artistically] mich 4-26-19
My Dear Marjorie
I received your letter OK It was like getting money from home I am very glad your cold is getting better
I haven't got much to say only glad this week is over.
The hours did seem days. The days weeks while you were absent from me I wonder if you are as impatient to see me as I am to fly to you
I got home Sunday night all right but was very lonesome
I can still see you bidding me good bye
That was a very sad good bye Too so now Im going to say good bye Too
Unchangeably yours, Bud [last word underlined]
to my loving little girl with love and kisses [several x's]
P.S. Excuse poor writing and spelling because Im sleepy the clock is sounding two
Over [flip page, but not before noting at the bottom the S. W. A. K. found on most letters/envelopes, with the meaning lost to me].
As Unto the bow the the cord is;
So unto the man is woman
Though she bends; him she obeys him,
Though she draws him , yet she follows:
Useless each without the other.
Len. Bud. Longfellow?
