I do agree that having occasional arguments is healthly in any relationship. Although, couples that argue repeatatly and makeup, might not know when to call it quits. Which can cause them to be involved in a toxic relationship. Another issue with being argumentative is the affect that it can have on family members, friends and possibly work. By being in a relationship with constant arguing, others could be feeling fearful from hearing there constant bickering, not knowing what could happen between the couple and feeling annyoid knowing htat this could affect couple outings and ruin plans. Along with knowing when they break up there going to get back together again and repeat the cylce.
