uclife - I know exactly what u feel, but trust me - its far FAR better that you were honest upfront and he was honest (although lame/cowardly) back.
I have been in a relationship now for near on 3 years and everything was awesome till my colitis flare. Before the flare, I had explained what might happen and he was cool with it from what he said. This flare however has lasted 18 months now and has been very hard/stressful.
BUT, the nasty thing is that it turns out he wasn't so cool with it as he thought. Initially he was really supportive but as the drugs I was on increased and the dose increased I think he started to see what I had meant by turning my life upside down.
6 months he started to distance himself and bury himself in work. I am hoping that the talks we have been trying to regularly have are helping, but when someone who is the centre of your life and such a source of strength looks you in the eyes and tells you "I don't know if I love you any more", its rather devastating.
In future, I will make it plainly obvious to any future possible partner exactly what it may entail and I hope they turn me down rather then let me settle down with them, only to loose them to this disease again.
I really needed that... Rather cathartic actually
