I agree with the people below who say that these guys are just jerks! Anyone who reacts to something that is keeping you alive and healthy is just ignorant and small-minded......is that anyone you'd want to be with long term, anyway?
You WILL find someone accepting and wonderful, I promise! I was with someone for years, we were engaged, then he did a total 180 and said he couldn't deal with the diabetes. My confidence was shaken (more like destroyed), but I got back out there after a while, and I had some failed attempts at dating (jerks)...then found my wonderful boyfriend who is wonderfully accepting of my diabetes and all my related gadgets!.........It will happen for you too
