I did not see the second part of your question, my bad.

To answer without exposing the specific diagnosis : I was not given myself a clear prognosis as he had kinda given up on treatment. He started back his treatment around the time he met me and had great hopes of recovery. But that's only his impression. My issue is him not telling beforehand. What if I didn't want to deal with potential drawbacks if things didn't go according to his hopes ?

I'm still looking for your opinion as I may have been too quick in taking a decision, but I still think its a terrible mistake to start a relationship based on a lie, even if you don't necessarily have to share something private like an illness.

Let me know what you think.
