You think that saying your piece will help you move on, but in my experience that is rarely the case.
My ex-DP before the routine of break-up/make-up was amazing, caring and I genuinely loved him. The first time we split he begrudgingly agreed we could meet in person and talk because in my mind I needed to "say my piece".
I got to his car, got in and he didn't look at me, once. He didn't even speak apart from saying "you wanted to talk?". I said my piece, I wasn't overly emotional, I told him I wanted to listen, wanted to help him ... and he said "it doesn't matter what you think" and dropped me at the train station.
2 weeks earlier from that he has asked me to marry him and he had asked me to move in.
Something switched in his mind - men always do this when they're breaking up - nothing you say will penetrate the wall of silence he has made. And you will get more and more upset as you are confronted by yet more silence. And he was be annoyed at having to be confronted by your emotions. Sorry, I know that's tough to hear.
I wish someone had told me this before I got back with ex-DP, because it led to 3 more heartbreaks for me to maintain contact with him and need closure.
The closure you need is that he is an inconsiderate, immature and self-centred man who cannot for whatever reason deal with his partner's emotional reactions to his declarations about the relationship.
You did have a good relationship, but that ended when he decided to stonewall you on holiday.
I would not call him tonight. This is to make HIM feel better. Like it made my ex-DP feel better to send me an obligatory "happy birthday" message 4 days after he dumped me for no reason/explanation.
Start putting yourself first.
He'll be back, but I guarantee you won't want him.
