We all deserve/expect to have our needs met. Have you talked to him? Couples counseling would be helpful; if he won't go, go for yourself. You aren't doing anything wrong. Feelings aren't right or wrong, they simply are. Do you suspect there is someone else (sorry for that question), but when people change drastically, there is a reason. You are doing everything.....and he isn't...as you said, he is "selfish"---so wrong. You will begin to resent him (if you already don't)....a marriage should be about respect, love, etc.......
