Hi,
I was carefully reading your question and I concluded that:
1. Your boyfriend does not want to commit to you, you are the ones making the wedding plans.
2. His statement " Why do you want to _f___ a good thing? He does not want to marry you or anybody.
You were together for 11 years
and he did not make up his mind of giving you an honorable title and status of MRS in front of his last name .
3. He did not even propose to you. How can you marry if there is no
marriage proposal from a man? I know we live in a modern age wherein women are more aggressive but not in this instance.
My dear, if you were my sister, I would tell you to pack up your personal belongings, leave him there and find yourself a man who will respect you, not take you for granted and will honor you by making you his WIFE.
Your man is not a man, he is still a BOY and you certainly do not want to marry a BOY.
