Most Helpful Guy
It may be important to analyze why you may miss that behavior. For instance, when a couple is screaming and yelling and fighting with each other it releases hormones into your body to deal with the stress. It's kind of like it's own high. You feel alive even if you're not particularly happy. It's probably that that you "miss", you became used to conflict and now you are without conflict. Role playing with your new boyfriend may help you gain some of that feeling back without associating it with your old boyfriend.
