Is there such thing as healthy arguments or healthy amount of fights?

My SO and I agreed on a break due to excessive amount of fights and arguments and on top of that..his tendency to act single sometimes.

Whenever you guys fight, how does it end? How should it end?

Sometimes we cuss each other out or sometimes he will call me crazy or anything along those lines, sometimes we leave for hours and pretend nothing happened, sometimes we just drinks and smoke it away, but that never solves anything. I need real advice.

*No I will not leave him, I need some input on you guys relationship since this is my very first and I wish to make it my last, we have been dating for a few years if it matters and are engaged*
