Promotion came too late

I received the announcement from the management last week, that i have been promoted to an asst manager position beginning from Jan. I am quite numb to my new title and not a single tinge of excitement is felt. It came too late after my ex boss has resigned and gone back to Singapore. He has been trying hard to get me promoted, and i am not ambitious enough to take up the position.
After he left, i have to face the harsh management style from the local china ppl and i just do not like it. i have no motivation to continue in cold and wet Shanghai alone. I am in my mid 30s now, i just hope i can settle down with someone who is already my kin, and i want no more challenges for me. I feel old.
