should I confront him?

Wednesday, my Bf told me he was going to meet up with a friend after work to talk for a minute. Just now I found out it was his ex-gf who he has a child with. He didn't tell me about it or anything. & now I'm realizing that when he came home Wednesday and we had sex he couldn't cum. Which he always does. Should I confront him?? 
Ps: he's cheated on me with her in the past.
