Why did he cover my cleavage?

I know it sounds stupid but I just can't figure it out. Haha.

My boyfriend and I were making out and I was laying on top of him. I was wearing a baggy shirt that came pretty low I guess. While we were talking and I was still on top of him he sometimes covered up my cleavage. But then at another point he reached up my shirt, undid my bra, and started feeling my boobs.

So I'm really getting mixed signals. Does he not like my boobs or was he telling me to wear a not=so-low shirt? Like why didn't he want to see them? Please help me.
