no affection

my bf shows me no affection anymore. not the kind im looking for. we have tons of sex but it's not making love. it's like he fucks me just to get his rocks off. i do enjoy sex with him but wish it was less sex and more affection! he use to do tons of affectionate things , like hold me just bc , buy me flowers to say sorry , get me jewelry. i am not looking for the material , it was that he thought about me to do those things & now it's dead. he shows very little affection and when he do it's just when he is ready to have sex... idk wht to do or tell him!
