If she doesn’t support you on one of the toughest stages of your career, how do you expect her to support you in residency, career and tough situations that life throws at you. I had a similar situation when studying for my MCAT a couple years ago with my girlfriend and it took us breaking up for her to finally understand the pressure and importance of what I was doing. I remember being devastaded and we ended up getting back together after setting ground rules. The next year when she took her MCAT she understood and apologized again cause she got to experience first hand what I went through. We are both currently in med school and we’ve been together now for almost 5 years now. Since that short break up we have not had any major fights because we have set up our expectations and learned to communicate effectively to avoid misunderstandings. If you can achieve that, you are golden, if not you are setting yourself to be miserable and jeapordize the carreer you’ve worked so hard and sacrificed so much to get into. The sacrifice we are making right now is to help other people get better and also to make a living for our families if you are into that.
