Should I be mad he’s talking to other females?

Recently I caught the guy I’m supposed to be working on a relationship sitting in my bed asking one of his friends to text females for him on Instagram he told me he was just being sarcastic and he wasn’t looking for anyone else before all of this happened he told me he loved me and really wanted our relationship to work out

Why would he tell me he loved me if he’s looking for other females to talk to
