My (26F) bf (34M) used my phone and discovered I’m feeling unhappy in our relationship so he dumped me. How should I approach the conversation?

I have an iPhone, my bf Android. I’m 26, he’s 34. Background: we’ve been together 4 months, but known each other for almost 2 years. In the last week I’ve been having feelings of unhappiness and just haven’t felt myself. I came home from work one night and he was cooking and I had the thought “I don’t know if I can picture myself with him forever” which is unusual for me. I don’t usually have doubts like that but it’s been weighing on me. I haven’t mentioned it to him.<br><br>Last night I was driving him home and he wanted to look at a video in a text from a friend. I handed him my phone and he scrolls to the wrong message and sees a convo between me and my best friend.<br><br>I asked her “Am I stupid?” In reference to something specific but it’s irrelevant. She responds “no but maybe be careful talking to him, I don’t want you saying stuff you’d rather keep to yourself.” I replied “I always be careful lol.” But a few minutes later in response to her message I messaged “I’ve actually been feeling unhappy with him in general and I don’t think we’re gonna last any longer than the next couple months so I’ll be out of this relationship anyway but I don’t wanna lose him as a friend; he has no stones to call me out on anything so I don’t think he’ll see it that way but I’m gonna be more careful and try to see it from his perspective.” Then I said “I’m not gonna mention it again but I’ve been unhappy in general for the past week or so. I don’t like feeling unhappy with him but I’m trying to be understanding of myself and not judge it.” I haven’t mentioned it to her or anyone else since.<br><br>So he sees this convo, and messages my best friend himself (who my bf knows but not extremely well). He’s like “I hope this isn’t you talking shit about me. Really hurtful.” My best friend responds and tells him that he shouldn’t be on my phone and that he has no right to accuse her of anything. He calls her a bitch and gets mad at her which is totally uncalled for.<br><br>He then texts me (from my phone) asking me if I was gonna “blindside him and leave” and that he “can’t be with someone he can’t trust.” He then takes my phone and leaves the car and doesn’t answer my calls and texts for hours.<br><br>He finally answers and tells me that he’s done with our relationship but still wants to keep me in his life and stay friends. I told him it’s not gonna work out like that but he was being stubborn. I finally told him I’m not comfortable talking about it on the phone and asked if we could talk in person and he said it was final but then eventually said okay. He told me he didn’t want to see me til the weekend so I said okay.<br><br>I plan on explaining to him that I’m not typically one to doubt relationships and when I feel unhappy, it’s not with him, just in life, and it’s uncommon for me. I want to say that it was just a weird feeling that I didn’t have context for, and that I don’t think I should be blamed for voicing something that I’ve never experienced before. I plan on explaining that the message about being unhappy was about life and him just happening to be in the picture; he’s not the cause, but maybe the catalyst for experiencing it. I want to say that it’s possible I was projecting, and it’s something I’m willing to work on. <br><br>And I’m gonna apologize for the part about him not having balls to call me out, because while it is true, it’s a pretty shitty thing to say. I want to explain that I didn’t mean it maliciously. I want to apologize for hurting him. And I’m just gonna go from there and see what he has to say.
