Am I being manipulated?

me and my situationship got into an argument today.
he basically was entertaining other women on Instagram, while telling me he wants me to wait for him and how important I am to him and stuff like that. I got mad and said something to him, but now the problem is no longer an issue I have, he's trying to tell me it's over because of how I went about having an issue, instead of the actual issue, which never got solved. he's ignoring me now and he won't listen to my actual problems.
did I really make a mistake? Because I don't feel like I did, or am I being manipulated into not being listened to?
