different situation, and maybe people will hate me for it, but ill put this out there for the sake of showing a different perspective.
never married, but was engaged, and we lived together for a year before splitting up. From day one my partner knew that medicine had been my plan for a long time, my dream that i worked on for 4 years before the relationship even started. at first he was excited (he was from a very wealthy family, and dating a doctor was cool. I am dirt poor, immigrant, but i have 3 degrees, play musical instruments, educated in art, finances, science, speak several languages, blah blah blah, so i was a "good fit" for the family. they cared about this cr**). Then, as i was going through the application cycle, and finishing my last year of college (my second bachelors in biochem), and working full time in addiction treatment facility and as a TA, he started getting upset that i was not there enough. But while he was complaining, he wouldnt do anything to help make time... For example, i was still expected to cook, take care of the animals, etc. I would ask him "well, if you fixed dinner, i would finish up, and we can spend time together".... he didnt see it this way..... I was still expected to do everything in addition to my work and school load... "because he was tired from work" (he worked only 40 hours a week, while i worked 40 plus school plus travelling to interviews). Anyway, there was a week when i had flu. 102 fever, all the works. Had to go to work, school, all of it. Came home at 10 pm.... he was about to go to bed to get his 8 hours of sleep.... There was nothing for me to eat, dog was not walked. I ended up staying up till midnight making dinner, walking dog, feeding her, and studying with 102 degree fever. Was up at 6, - 30 min before him.
then he started getting jealous and say how i "got lucky" that i got into medical school. LUCKY???? anyway, you can even imagine how mad i was. As the time to move for medical school was nearing, our relationship was collapsing. he didnt even congratulate me for my birthday. He became jealous of my success, and that i achieved the goal i was working for. His mom told him that she never thought i would actually get in (because she didn't back in the days). Anyway, everything just turned into resentment, cruel comments. He was saying that i was heartless because i took MCAT after my brother died (instead of taking several months off to grieve - i couldn't even afford to skip one day off work but being the rich kid he didn't get it). anyway... things went really bad.
we split up in May, after i finalized paperwork with EVMS. In July i moved to Norfolk and never looked back.
What i learnt from it (just for myself, i am not saying that this is what you should do, i am just sharing my personal experience): If your partner is worried about general stuff, but loves and supports you, - work on things. If the partner starts getting jealous because you are more successful, or resenting you for achieving your dreams while they maybe failed (so dynamic changed in the relationship), then walk away and never look back. Thats just my experience, of course. I just realized that my own life that i worked so hard on building is more important to me that someone who doesnt understand.
PS: me and him talk once in a while, and he admitted that he was definitely wrong, and he is sorry. Now i see that splitting up was the best thing for both of us.
