A person with ADD can be wonderfully romantic when starting a relationship because he or she will hyperfocus on the person. But when that relationship is established, then their focus can shift. It doesn’t mean he loves you any less; it just means his focus has shifted.
I would try telling him how you feel, and asking for specific time or energy. My spouse literally forgets that I need attention. When I point out that she gives her email more time than she gives me, she tries harder to pay attention to me. Try setting aside the same night every week as ‘date night.’
