Break up after residency? Is this a thing?

My 36m gen surg resident ended with me 2 months ago - pretty out of the blue. Three months after finally passing his surgical training and me dedicating the last year to him so all he had to think of was study. Despite my big corporate job too.

Friends for two years, dated for two years. Went for a walk, said he didn’t see us getting married and having kids with me. Obviously I was shocked, as that was sort of the plan ha - we were moving to another country for fellowship next year. I walked back to my house (hadn’t moved in together as study schedule obviously). And he said he’d put my stuff in a bag - spare tampons, contact lenses and as he walked out the door said “I’ve written your medical note to get you a refund on your flight” (I’d booked flights for a a holiday three days before. Totally blindsided. Haven’t heard from him since apart from him replying to a text which his reply was “I do not love you, we are broken up, move on”. Blocked everywhere. Cut. Surgical precision.

When you spend all this time supporting someone to hone their craft, you don’t except to be the one they cut out so meticulously. He’s been working crazy hours post exams, every weekend - had a rash on his face from stress and was getting now sleep. We were finally going to get weekends back in sept after every weekend for the last year or so being study time only annd then broke up with me last few days of August..

Talking to my therapist; she said she had heard of this happening to another person. Is this a thing? Do you know of people that have basically used someone through exams and then gotten rid of them?

I am a very happy, successful, emotionally balanced 35F - and this has thrown me and my friends/ family so much.
