How can ADHD, such a common affliction, which he didn't even notice himself, be such a case for unacceptance?
Perhaps rather than say I'm ok with being 'deceived' what about you think of the fact that exams are very important. She could have messed up her own exams as well as his. It was the most logical course of action that was best for both.
Besides, how is it deceiving when it is an affliction that is evidently not even too obvious. Are you supposed to tell your girlfriend if your right hand pinkie is longer than that of your left by 0.5cm? There was no deceiving. He didn't say 'i have no adhd' to later state otherwise.
If he can't see that 1) the telling after exams was by far the best thing to do and 2) that adhd, a common thing and one he didn't even seem to notice is of little matter, then I don't think he is the best of partners
I understand your pointing out of the contradiction, but not accepting someone because of previously unnoticed ADHD is very different. And then again, they had been together only for 6 months. It takes time to open up to things. And as anon has seen after these 6 months, her bf does not seem to be the understanding sort at all, which yet again proves why it tends to take time for people to open up.
Again, it would be pretty inconsequential that she has adhd anyway. There was no deceiving. It's just that a common, and apparently unnoticeable ailment affected her, which makes no difference to the relationship. Him not being understanding gives shows her to have been correct in not wanting to open up.
