Feeling unloved

What do you do when you're feeling unloved in a relationship with a man you're living with? He always literally every night goes to bed without me and doesn't even say goodnight. What boyfriend does that? Sex is either fucking amazing or horrible. No in between. He doesn't try to do sweet things for me anymore. He never texts me while I'm at work like he use to. Idk what to do. I guess he just isn't putting in any effort anymore even tho I have been trying to put effort more than I ever have before. Help?
