Is this the end?

I've been in a 2 year committed relationship. Never once have I ever cheated on my boyfriend. On New Years, I came home from work, and someone was blowing up his phone, at 2 am. Which if it was anyone important, they know that he works 12-15 hour days, they know he is sleeping. So, me, I looked at his phone and it was messages from some girl on a whisper app. I opened the messages to find exchanged photos, inappropriate conversation, and heartbreak. I confronted him and he said he would never do it again. Said he didn't know the person and just got bored while working, and started talking to people. He promised me he would work on him, and things were great. Until this morning. He got a new phone under warranty, and his other phone was going off (while connected to wifi) in his closet. I didn't even know he still had it. And low and behold. I find the same thing. Again. My heart is broken and he swears I didn't do anything and he doesn't know why he did it. What do I do. 😔
