Switched emotions? iin?

me and my boyfriend have been together for almost a year, since Jan first of this year.. When we first started going out I loved the way he cared for me but I guess I didn't like him as much as he liked me cause he claimed I blocked myself from him.. So kinda secretly towards himself he grew less caring and so I grew more caring.. It's like we switched parts. Things began to hurt me more now that he started to do little things that had bothered me deeply.. I confronted him barely a couple of days ago and now he feels sorry about everything and the day after he poured he's emotions out that he would try and care about me more and then next day he was being unkind to me, I told him I was falling for him. I've never liked someone so much neither been with anyone for this long.. I had felt heartbroken that instant.. I had poured my heart out to him. He felt very bad and he says that he's trying I know people can't change in a day but if he truely cared for me he wouldn't have to try.. But from being the one blocking someone out I felt like I was doing nothing wrong, I know how he felt at that time then. I feel miserable. I then told him we need time to think but not to see other people, just a time for ourselves.. one week. i know people do these things for to think if they should be together or not, but I don't know what's on his mind.. For now I'm preparing myself for both outcomes. Is this normal? To have switched emotions?
