Guy friend accidentally grabbed my boob?

So me and my friends got pretty drunk yesterday and my guy friend was saying something and i was looking the other way he tried to grab my arm so that i looked at him but grabbed my boob instead and kept the hand there for like 3 seconds then i looked at him in shock and pushed him (very lightly) and he started laughing and looking at the floor cos he couldnt say what happened but he started to go a little red in the face. Is he into me or was just embarrassed?
