1. You're in a relationship, or you've been in one before. You get into a fight or misunderstanding with your significant other...does fighting help? That would depend on what is meant by help. Fighting does most certainly help me feel better. It certainly beats the hell out of holding my feelings in. But very few problems ever got solved by fighting, so in that respect it is very little if any help at all.
2. Do you fight fair? Does/did your partner? Or is/was it a big game of 'he said, she said'? Hell no! I don't fight fair, I fight to win! Unfortunately the insignificant other uses the same method. But I do have limits to what I will do. I try to avoid using my children as weapons. I wish I could say the same for him.
3. Did you ever have a disagreement so bad, you thought 'this is it' for the relationship? What happened? Many times. My relationship with the estranged one has always been an on again off again kind of thing. We've tried again more times than I can count. The result is always the same, we can't bear to live with each other. It's the "children as weapons" thing that prevents me from filing for divorce. I just don't want to deal with the ugly custody battle that he has promised to put up should I do so.
Bonus Question for Comments: When you've been fighting with a loved one, how do you make up (No, it doesn't have to be someone you're involved with)? Sometimes it is necessary to apologize, even if you don't believe you have done anything wrong. If it has been a particularly bad fight, a little gift doesn't hurt either.
