<human>: Hello everyone, I'm just in need of some advice.

My ex and I started seeing each other our final year in high school and although we maintained a long distance relationship for two years following, it was going quite well. 

However, about a year ago my liver failed while I was away at school. I was rushed to the ER and treated. The Doctors never found and reason or cause for the failure which was troubling for them.

(Just to mention I'm in pretty healthy shape, by no means an Olympian but an average guy!)

Needless to say it was quite a scare, one I never told my ex about. I ended up putting the incident on the back burner until a month later when I was contacted by the hospital again and was called in for testing as they were worried there may have been an underlying trigger. Long story short it concluded with a a diagnosis that had a strict regime of transfusions and continued surgery. 

The treatment plan was set to last for the better half of a year, but after a month I felt like the treatment in combination with my schooling and long distance relationship was too much. 

I broke up with her, probably used some canned excuse but never told her the real reason.

One year later and I've recovered for the most part, and still have feelings for her. Is talking to her a bad idea?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Was diagnosed with a rare liver condition which involved a long and grinding treatment process. Ended our 3 year relationship, and now that I'm recovering I whole heartedly regret my decision.
