What does it mean when my boyfriend tried to break up, but backs away so we did not and then he starts holding around me?

My boyfriend for 5 months have been feeling uncertain about me, and have been asking me how I feel for him. And I tried to ask him if he wants the door is right there, and then he backs away of breaking up and we both said that we are going to speak in a few days. Then he starts holding me all the time, and holds my lower back and oldmost touching my bum. What does this mean?
