Just broke up with my boyfriend.

So, Just a day ago, me and my boyfriend broke up. He acted weird when I touched his phone only to play music. He was very annoyed. They puzzled me. But later that night, I texted him about this issue. He told me it's a family secret. But I don't understand how that would be all over his phone? Maximum would be me, checking his whatsapp chats which I don't like doing because I value privacy. He was the opposite, used to read me and my friends convo.... that's disgusting right? He stoped texting me at one point and blocked me on all social networking sites. (It had been only 1 1/2 months that we started dating And to add on it, he was a random tinder dude)
