boyfriend broke up with me over Snapchat

My boyfriend broke up with me the other day due to social media, but he say that he wants us to be friends until we can figure out how to trust eachother. But a couple months ago I found him talking to a girl on social media and sending her memes & she told him she loves him. So I couldn't trust him, he seen a guy text me good morning, but the number wasn't saved in my phone and I lied about it at first & pretended like I didn't know who it was. Then we obviously couldn't trust eachother. So we deleted our snapchats. So we got into a fight and he said that I can have my Snapchat back, so I made a new one, he found that I made it & put it in my bio on YouTube. So he said he couldn't trust me and I was being sneaky, but I feel like it's more to it & he wants to do his own thang
