Throwaway because reasons. 

My partner and I have been together for 4ish years, currently living together. Starting in the fall, I'll be moving about 3 hours away for graduate school (Not the issue, we had anticipated this for awhile). 

The problem is that when I went to meet with my new advisor very recently, I was presented with the opportunity to get a drastic head start on my thesis with a 5 month field season roughly 6 hours away and starting in May. So now instead of five months to plan and be together, we would have 2 and will see each other pretty rarely for awhile. 

This is the person I want to spend the rest of my life with, and I can see this is really hard on him (it's pretty hard on me too tbh). Every time I mention it I can see it hurts them. However, we're both still pretty young, and this is an amazing career/personal opportunity for me to finally be following my passion. 

So reddit, AITA for being selfish and seriously considering this?
