You have all the support here you need.

This is not something that you can "fix". And likely if he's done it to you; he's done it to others in the past; too. And in a lot of ways I am glad for your own safety that he lives no where near you.

What you have described is not a little shove. It's a serious assault. And if he does it when he's drinking you have no control over when he takes it one step too far; you land up in hospital; or worse ... You asked if it will get worse. And I'm certain it will.

I have no doubt you're anxious. And I'm sure that he has admirable qualities which attracted you to him ill the first place. But this relationship is not one that is sustainable. Keep your distance.
