Did I make the right decision? 💔😭

So my boyfriend (ex at this point) and I have been pretty rocky these last couple months. We had been together for about 3 years and then things started getting bad. He just seemed to do a totally 180 and was suddenly not the guy that I had first met. So we decided that it was for the best if we broke up. This was in January. We ended up getting back together in early May. However, while we were broken up, he had dated another girl, I'll call her Becky. (Nothing wrong with him dating someone else, we were broken up after all. Just putting that in because it's pertinent to the later part of the story.)

Anyway, so since we got back together in May things were good for a little bit and then he reverted back to how he was when we broke up previously. Obviously I care deeply about him and wanted to make it work so I stuck it out.

Fast forward to about 3 weeks ago, we are on vacation with my family up in the middle of nowhere. Things are going really well, we are having fun together and are happy. Then, one day I'm in the room that him and I are sharing, organizing some stuff in my suitcase and his phone vibrates. It's on the nightstand and of course I'm curious. Normally I wouldn't snoop but it was right there. I don't know the passcode or anything, so all I could see was the lockscreen but his ex, Becky, had texted him. I was a little irritated but did not want to jump to conclusions so I decided to ask him why she had reached out later that night. When I asked, he said that she had just said "Hey" and he had ignored and deleted the message. Okay, no problems with that. But now I'm curious so the next morning, I'm noisy and I look again. She had texted him twice. Once late the night before and the once again that morning. Now I'm kind of suspicious. We go kayaking that day and while we are out on the water, I approach him about it. He explains that he isn't sure why she has texted him again but says he'll let me see it when we get back (he had left his phone where we were staying). We get back and I'm talking to my family about how kayaking went. After I'm done telling them, I go into the room we were sharing, he's in there and looking at his phone. I ask if it's okay for me to see the messages now to which he replies, "Well, there was nothing important in her messages so I deleted them." Okay, that's kind of weird to me since you told me I could see them and then deleted them. Now, i'm thinking he is hiding something but wanting us to enjoy the vacation, I let it go. That night, we go out with some friends and family for dinner and when we get back, I'm in our room changing and his phone vibrates on the nightstand again, so I look and it's her again! This time a Snapchat. Eventually, he comes into the room and I ask to see what the Snapchat is of. This results in a big fight.

He refuses to show me the Snapchat and says I should trust him. Which I agree with but he gave me a reason not to trust him when he said I could see the texts and then deleted them. I tell him that I do not trust him after deleting the messages and being sneaky about this. We get into this giant argument, me saying I want to see the Snapchat and him refusing to show me. He called me a c*nt, said f*ck you to me, and said that he felt I was unattractive and that's why he had changed. So I told him he could leave after those comments.

We have talked since then and he says he just said those things out of anger and that he really did have nothing to hide with Becky and I should have believed him. Regardless of the Becky situation (which is still find sketchy), I can't get over the names he called me and his rude comments.

Did I do the right thing in telling him to get lost? Or should I have handled this differently?

I'm still really hurt by this because I do care deeply but feel that I deserve to be treated better. Besides telling me over text that he is sorry, he has not once picked up the phone to apologize or shown up. He has not put any effort in to show that he is sorry so I don't think he really cares? I think I'm just making a fool out of myself:
