Thoughts?

I’m gonna try to make this as short as possible. My now fiancé (been with him over 3 1// years). Been living with him since 6 months together. Probably about a year and a half ago he had to stop working and get surgery and he has friends but obviously nobody that would take care of him and he has family but they don’t live near. I was working at the time and would try to come home as early as possible and I was taking care of him and waiting on him hand and foot anything he needed to help him back on his feet. I was really the only one there. No questions asked. I was there for him as I feel a gf should be. Took him a few months to get completely back to normal and I didn’t mind because I love him and would do anything to help him. I was cooking, cleaning, working, waiting on him. Anyways fast forward a year. My mom is in the hospital for something very serious. We were going through problems at the time and weren’t on the best terms because we were thinking of possibly breaking up. I was 2 hours away spending night and day in the hospital for like 2 weeks and had hardly any family support and was the only one taking care of her and I had hardly anyone to be there for me. I was dealing with all the doctors, stressed out not knowing how I’d get my moms bills paid with her unwell, and just worried above all that she wouldn’t make it or something. I know we were having problems but my now fiancé wasn’t hardly there for me. He was in school full time and 2 hours away I understand he couldn’t be there to support me but the fact that just because we were having bad problems he can’t even barely check in nor ask how I’m doing and be there for me? If we were doing bad in our relationship and something happened to him at this moment I’d be right there to help him no questions asked and the one time I go through a tough time and he can’t even be there for me? He would always tell me school was a priority and came first before anything cause he was full time and close to finishing and couldn’t miss class or assignments so I understand but the fact that he couldn’t even check in or send a text here and there to see how I was doing seems really fucked up to me. I talked to him about it at the time and he made a day to come visit and try to be there for me but I could feel it was forced and he wasnt even happy about it so really it just irritated me more having him there to pout and have this tension while I was already dealing with a lot with my mom. This happens last December and I still have resentment towards him. I’m not saying he HAS to be there for me cause I was there for him. I’m saying I would do anything for him and go out of my way yet the one time I really needed him for support he couldn’t even genuinely be there for me.
