Update: My [24F] boyfriend [26M] had a secret meet-up with his ex while we were on vacation together with my family. We split, but he’s being manipulative about it and blaming me

So I asked him if we could meet up to talk. We took a walk and I asked if he had anything he was keeping from me that he wanted to share to which he adamantly denied he did. So I confronted him with the evidence. He immediately got nervous and guilty but said “it was no big deal†and that I was “overreacting.†I asked if that was the case then why did he lie to her as well and not be upfront he was staying at my parents house? He said because a part of him always had feelings for her.
I went off said I’m not here to be lied to and played and made a fool out of. Said I’m not ****ing stupid and so I’m going to need to move the **** out. I went back inside and packed a suitcase and I’m currently looking at flights out of here.
That night he was super apologetic, saying I’m so sorry and asking what he can do to make me stay, to which I said nothing.
Next day he came in and said it was “disgusting†and “immature†that I went through his phone. He said he consulted both his friends and the internet and they can’t believe that I’m ending things over this and that he should break up with me just based on the fact that I snooped. He also said my reaction to want to leave is just proof that we’re not meant to be together because if we were I would forgive him. He keeps stating that we’re never going to see eye to eye on this and that we have different priorities and are incompatible. Why doesn’t he just accept the fact that objectively, it was deceitful and inappropriate for him to have done that? Now he currently has a laundry list of everything I did wrong in the relationship to justify what he did. He said he was never happy with me even though to my face he behaved entirely otherwise. I’ve never been so disgusted and disrespected by someone in my life.
Thank you to everyone who helped me in the original post and their amazing advice! If only he had posted in here when he consulted the internet, maybe he would have gotten some decent feedback. I’ll be flying far away from this duplicitous manipulator in less than two weeks.
TL;DR Update of previous post in which bf met up with ex while we were on vacation with my parents for a secret lunch. I caught him by looking through his phone and now he’s blaming me for the breakup and I’m moving out ty r/relationships
