scarletB,

In my opinion, I would consider it very important to know all the details of his injury. If you hope for a long term relationship, his history needs to come out. You can be much more support for him if you understand.

These injuries are often very complex. Researching the symptoms and then trying to diagnose his condition without him being open about his injury puts a heavy burden on you and strains the balance of your relationship.

Statistically, 80% of relationships/marriages interrupted by a brain injury do not make it. I am not trying to rain on your parade. I just think it is important for him to be open with you so you can be proper support.

My best to you.
