Catholics Please answer this?

This is about a friend of mine (thought was a friend) He hadnt been to Mass in years and when he met me he started going with me but Obviously he couldnt recieve Holy Commuion. I told him if he wanted to go to Commuion he would have to go to Confession first. So after a while he told me he went to confession so I let him go up to Communion. But A while after that he told me he lied about going to confession. Im worried for my soul (even though I know its not my fault) I am very worried about his. What do I do
