No, he's spent the decade grooming you to minimise it the first time it happens.
And then it will escalate.
That's how abusers work. He has been undermining you, making you feel like shit, telling you your work is worth nothing and then the final blow is that he pushes you and when you push back, instead of realising that he'd crossed the line, he ups the ante and makes clear that he's prepared to be very violent to slap you back into line.
Please do not minimise this. It's classic. Abusers don't start punching you the day the meet you, you'd call the police immediately and dump their arse if they did. They work up to it, sometimes it only takes a few days, sometimes weeks, months, or years. In your case it has taken years for him to feel safe to do this to you.
And they don't start punching you, breaking your ribs and stabbing you. They start with minor attacks like this one - a couple of shoves. A push here and there. Walking into you. Standing on your toes "accidentally". They push the boundaries further and further out.
He's started with a couple of shoves. That's how far he can go atm. If you don't show him that he's gone too far, he'll just push the boundaries further. He may stick to shoving for a few weeks or months. But not forever.
Please, take this seriously. Call the police.
