Newbie needs feedback.

10 handed. .5/1 NL UTG, UTG+1, limp. MP1 makes it 5 to go which has been standard raise. MP1 has raised before and check folded flop. MP3 calls with $230, CO calls $18, Button Calls with $180. Blinds and limpers fold.

Pot $25 Flop comes:
235 rainbow

Checked to button bets 14. PF raiser folds, MP3 min raises to 28. CO goes all in. Button reraises to 65. MP3 reraises to 110. Button pushes and MP3 calls.

Hands: MP3 55
CO 22
Button 46

I believe this is a standard play but am inexperienced and wondering what people have to say from the perspective of the button and the MP3. Even if your feedback is: this is obvious it is appreciated.

Cheers!
