Boy friend tapped my cell phone?

So I’m starting to think my boyfriend maybe tapped my phone...There have just been too many coincidences lately. A customer at work brought me a card and gave me his number, I hadn’t told my bf yet but I had told my best friend because it’s flattering.... no intention of texting him. Well supposedly the same thing happened to my bf and he sent it to me and said “Just want to let you know. I’m not hiding shit from you” I just thought it was a weird coincidence and the only person I told was her and through texts. Is it possible for him to bug my phone?? I’m so paranoid I’m posting this on my iPad! We don’t live together but I’ve spent the night, there’s no weird apps on my phone either.
