<human>: So I don't mean to be a sappy person here on /r/relationships, but I really need your guys' advice on this topic. I'm heartbroken and you've helped me in the past, so I'm here again hoping you can do the same. 

We've been together for a long while now, and we've been all over each other, happy, and each others' best friend. We've had our arguments, our 'this isn't going to work anymore' only followed by hugs and makeup sex etc, the usual. This last week has been extraordinarily rough. I've been battling a tough sickness for the last 6 months - which has put a strain on our relationship, but this time last week I was admitted into the hospital with a serious kidney infection which kept me there for several days. Afterwards, I stayed at his apartment (because he wanted to take care of me) up until today. It was a strenuous week - him working a full work week with me in the hospital, and me being in the hospital and trying to recover. Once I was up and okay to walk around, I tried to clean up his area of the apartment and make things a little less-stressful, because I know how much pressure he's been under this week. 

Today was finally his day off and he's been putting emphasis on how nice it's going to be after a week of all this, to have a day off and spend it with me. After him getting slightly frustrated that he was exhausted and I wanted to get out of the apartment and do something today, and argument ensued to the point where he said "I just want to be alone, I don't want to be in a relationship anymore. I don't want anything" completely out of the blue. He drove me home, dropped me off, deleted me off Facebook, everything. 

I'm heartbroken (and still sick) and just completely devastated. /r/relationships: today I lost the one I love most and he just up and left my life. I'm completely lost for words and have no clue what to do.

Here's a picture of us from the 4th:

<bot>: Broke up with the love of my life today during a not-so-great health time for me. Need advice on how to fix this.
