BF hates Snapchat

My on again off again bf hates that I have Snapchat. I’m honest and I tell him yes I talk to ppl on there but it’s not in a sexual manner. Or anything worse than him going to another female for advice. He calls me out of my name gets upset and then goes to the same female that wants to build a future with him. We’re both in our 20s almost 30s. I think it’s ok to talk but when you cross a line and make it sexual then it’s not ok.
