Tell him how you feel, and he'll either say sorry for making you feel that way, he didn't realise he was being distant. Or he'll admit he has an issue and it will open up discussion. But if you wantto do something to get his attention first, cook him a nice meal or take him to the cinema. When I have this problem, going somewhere new and exciting helps, or even a picnic or holiday. And, if all else fails, a fancy date or night out works, you'll both be dressed up and remember why you're so attracted to each other!
