Fighting, if it's serious or physical, no.

However, arguments and disagreements are natural. If you're in a relationship where there are no disgareements, then either someone's a pansy and won't speak up if something is wrong, or you're dating yourself- either way is unhealthy or boring. Healthy couples can survive differences, and are better for them.

see, sometimes a hoe gets outa line and you have to... lol, just kidding.

Fighting is fine as long as no one pulls a knife or ends up with a black eye. It's far worse to hold things in, or take out your anger in other ways.

Of course it's best to just talk things out, but that's not always possible. Plus angry sex is fun :)

Obviously it depends on what is meant by fighting. I will define fighting for the purpose of this argument as negotiation that requires strenuous effort.

I am of the persuasion that fighting is essential to healthy relationships. Each person has values and boundaries that need to be respected an unviolated. These vary greatly in their relative negotiability. Fighting like anything can be taken to unhealthy extremes, but being greatly challenged by those close to us is in my opinion our best opportunity to make improvements to ourselves and our relationships. what is unhealthy is when there is complete dominance in a relationship and cowardice and subordination define it.

Real fighting is not healthy for any relationship. An argument here and there in one thing but people need to talk things through and not fight to the bitter end. All is NOT fair in love and war as far as I'm concerned. You can damage a relationship for life if you fight all the time and neither one can take the initiative to say whoaaaaaaaa, let's sit down and talk this out. Sometimes what you say in the heat of the moment cannot be taken back no matter how much you apologize.
