My first thought is "Is this typical of your father througout your relationship or is this something new?" If he's reacted like this to things you have done all along, it IS very hurtful, but not to be unexpected. If this is a new reaction, perhaps he's always been complimentary and supportive, then purhaps there is something else going on. I know as my parents age, there are behaviors related to medication and/ or aging/ dementia that have made them react differently than I would have expected. Just a thought.
