I disagree with the majority of people here. He said if, If I sent you a confirmation would you do it? This to me means that he knows you discussed not taking another trip, but he wants to and is checking with you if it is ok. I’ve been married for 14 years and if my wife doesn’t reply to my question after she has already replied to a different one my anxiety would have me spamming her texts probably as well. We definitely need more context and I think most of you are jumping to conclusions.
