Am I crazy?

I have been with my boyfriend for almost 5 months, and yes we just started living together… that’s how close we have become, but lately I have been having some emotional issues. In a previous relationship I was verbally abused and by my father as well. I fully believe my ex cheated on me with the girl he is with now. I loved being single and planned o. It for the rest of my life like, I don’t have that desire to HAVE TO have a mate. I was good you know? Anyway I met this guy I work with and we became friends and then he asked me out and I said yes and that was it for us. Lately though some previous emotions I think I have been suppressing or something have been bubbling up and I have been like so emotional towards my boyfriend. He hasn’t said a mean word to me, in fact the opposite. I think he is backing away further when I really need him close to me. He is very quiet Normally but all he says when I try to talk to him is “okay” Lately I feel like he could care less (which I know is crazy) because he is showing me he does I’m so blinded by my emotions. This is so new for me , usually I am so in control of my emotions and like to have fun you know? I feel like I know the answer , just wanted to see if anyone has any other thoughts. I just didn’t feel I am getting what I need emotionally.. How do I communicate that? I know he loves me and he shows that to me, I could walk by him and he will brush my hand or kiss me or something it’s just I need more and I don’t know how to tell him. Also our schedules are different, maybe that’s it… also I’m 9 nears older than him. So I can’t really expect him to be where I am , but I am working through my issues. Kind words appreciated
