My lack of comprehension

My boyfriend asked me to promise him that if I don't understand something, that I will always ask him questions. After a long silence from me, I told him that I couldn't do that. I told him that it had nothing to do with me not wanting to promise or do what would help me, but that there are some things that I have no control of. He said that he understood, but would never hold it against me if I couldn't make this promise. There are times, when even I am not aware that I need clarification.

Sometimes, I silently cry because the sadness and frustration are just so overwhelming for me to deal with. I think that over the past eight years since my diagnosis, I have definitely noticed a decline in my comprehension.

Hopefully, as he and I spend more time together, that he will be able to pick up on the signs that tell him that I need an explanation to help me understand something. I will continue to do my best to educate him on what he needs to do or say to help me. Recently he told me that sometimes when he says something to me, I will become very quiet. I told him that I might be trying to figure out what he said, or find the words to respond. This sometimes will take some time and sometimes I will even forget what we were talking about. I think that I will usually say something to him.
