This is interesting as I'm the complete opposite -- when I was younger, I gave up on a lot of my dreams for the boys that were in my life. Now that I'm older and have more experience, I feel more able to say "I'm pursuing my goals, and would love for you to be a part of that, but if not .... sorry". It took a long time for me to get comfortable and confident enough to feel like I can survive on my own. I guess people work in opposite ways...
I don't think your decision is a bad one. Its really, really difficult to balance a professional and personal life, especially a professional life like ours, where we're not sure where we're going to end up, are constantly applying & pursuing goals, moving around the country/world for a Master's, Ph.D, post-graduate program ... Hearing the other poster's story about his/her friend working for an Ivy league, publishing papers & applying for grants without a tenure & without a relationship, made me realize that's not what I want at all. So as long as you can find a happy medium between your man and your career, even if that means making some compromises, I say go for it.
I think you hit the nail on the head - your bf is bitter about your decision. It seems to me that he isn't communicating how hurt he was by your decision to move and instead is acting out by choosing places even FURTHER away, to kind of say "Ha!! Take THAT! I can move, too!"
Of course, I'm just commenting as a third party but I know this all too well. When I announced to my bf last year that I was *definitely* leaving our current city & pursuing my Ph.D goals, he was really upset. So, what did he do? He signed up for his military service without telling me. When I got angry with him, he burst out "Well, you're not the only one that can make plans. I can make plans, too" That's when I realized he did it as a reaction to my announcing I was moving seemingly without including him in my plans.
After realizing this, I had a long talk with him. I told him how important our relationship is to me, and how it would mean the world for him to come with me. This didn't work like magic. It took a few weeks of more thinking on his part but it really cleared everything up. he realized I wasn't just packing up and abandoning him. Because that's what I think they feel like - like we're abandoning them. Now, he has never been more supportive of my decision. He will be done with his service in 6 weeks & he is actively involved in our moving plans. I try to keep him involved every step of the way so he feels like its his move, too.
So maybe, if you sit down with your bf and explain to him how much he means to you, how you want to be together, etc. it'll help you guys, too. Sometimes they just need to know you care, you know?
