I got a promotion!!!

Hooray! I got a promotion this week. It will be TONS of hours and lots of hard work, but the opportunity is amazing. Here's the story:
My boss, the sales and marketing manager, put in her notice the week I was gone for vacation. One of my co-workers, and really good friends with the owners, recommended me for the position. The owners were happy with my performance since I've been with the company (about 7 months) so they offered it to me! It's the same title but a slightly different capacity. Too much to go into unless you know my whole story, but I just wanted to brag on myself!
This leaves me really conflicted though... On Monday morning of last week, I emailed the contact for the UK MBA program that I was adament about getting into this year to talk to him about some questions and concerns. That very same day, I heard the news of my boss leaving and one of my other bosses mentioning they wanted to talk to me about a promotion. Rewind to last July- I got accepted into the MBA program the exact same time that I learned I had this opportunity with the company I work for now. Is some higher being trying to tell me that I'm not supposed to do the MBA right now, or is it a coincidence, luck, or crazy fate??? I am completely conflicted and would really appreciate any advice that someone would like to share!!!
