I think a lot of the problem is the difference between women and men. All the points about multi-tasking are true I think. It also may be true tho' that he has a slower processing speed - my dyslexic daughter has this and you have to wait for the info to be processed before you get a reaction or a response. She cannot multi task either and gets very focused on what she is doing to the point of cutting everything else out sometimes. It is very frustrating - my husband is like it too - we tell him he is not listening and he hotly denies this and will repeat what has just been said! He did not react when it was said, tho - how are we supposed to know he is part of the conversation? I find I converse much more with my girls than I do with him because I get a response! Maybe kids are the answer!
