I (30F) was offered a dream job across the country. Boyfriend (41M) of seven years, who works remotely, was initially supportive but now wants to stay in current city and believes my desire to take this position is selfish. I love him but know I would regret not taking this opportunity. Help!

Throwaway account for privacy. I would love to hear any thoughts or advice you have to offer. Here's more context
The relationship: We've been together for seven years, have lived together for 6, and have an 11 year age gap. I love this man with my whole heart and love the life we've created together. He is supportive, kind, and after being together so long we have grown a deep knowing of and appreciation for each other. However, for years I have been asking for more - for progression and growth and change in our relationship (marriage, kids, buying a home etc.) but he has refused to commit to any future plans. Our conversations on these topics go nowhere. We've been in a stalemate for years. I even broke up with him last summer due to his inability to commit to a future and a family. While broken up we still lived together and ended up reconciling after a couple months and he promised to change. We went to therapy where he said he is "open" to having a family and getting married but there has not been any additional movement since, despite my efforts. Meanwhile, we have talked about leaving out current city for a long time. He is from New England and his family is still there. He has expressed a desire to return to the area to be closer to them and that our current city in the midwest has never really felt like home. I have wanted to leave this city for a long time and began applying to jobs out East. My boyfriend was extremely supportive and even excited about this possibility when I was in the interview process. Now that it is a reality he is extremely upset and cannot believe I would choose a job over our relationship. He says he loves our life as it is and doesn't want anything to change and that I'm being incredibly selfish. I try to be understanding of his feelings but struggle to have sympathy - this move would be better for him since we would be closer to his family (further from mine), he works remotely and has total flexibility, and he has expressed a strong desire to leave this city for many years. I feel hurt and blindsided by his strong reaction.
The job: Would be a promotion, better title, and pay at a reputable institution. After meeting the team I feel confident this would be a great fit for me personally and professionally. It would launch my career into the stage and its geographical location would open so many doors. I can say without a doubt that I would regret not taking this job.
The dilemma: My boyfriend is hurt that I would choose this job over him and our life in the midwest. He's unsure if he would join me out east. I am hurt he's not being supportive of my aims and goals in life. Now I am waffling with this big decision.
TLDR: my long-term boyfriend changed his mind and is unwilling to move to the east coast (where he's from) so I can advance my career with a better paying job. Have any of you found yourselves in such a pickle? What did you choose and do you regret it?
