We have ongoing issues with the fact that dh just forgets an awful lot of things, conversations we've had, things I've asked him to do, things relating to family life etc and flowing from this, the fact that I feel he just is never really listening to me eg frequently I will say something to him and he will say the same thing back to me 10 minutes or even a day later, with no recollection that I have said this to him already.
We have talked about this before, I tell him that it makes me feel unimportant, ignored, unlistened to. We most recently had this conversation last night (after he forgot to come home to take our eldest in for his first ever day at school) and he didn't even remember that we've had conversations about this as an issue before 
No he doesn't have actual memory issues, he just says he doesn't have a very good memory. However, he holds down a very busy well paid job (ie 6 figures) so it is my opinion that it can't be that bad, and it seems more selective than across the board.
He says that asking him to address this is trying to fundamentally change him. I think that is a lazy excuse to continue to ignore stuff he's not really interested in.....
Any advice?
