Is it better to be alone and happy or together and

The title of this post is perfectly simple for me to answer but I wont do that right now cause I'm curious what others think.

Anyway, how many of you have seen couples who do nothing but argue all the time or maybe your own parents who cant stop screaming at each other because of money or other issues? I see it all the time and it makes me wonder why these people put up with it. Now dont get me wrong here, if you're married and have fights every now and then, I believe that is relatively normal but, if all you do is fight and argue all the time, why would you stay with that person?

The reason I bring this up is because I know a guy who is married. His wife has been a jerk for years and he recently found out that she had cheated on him with not one but four different guys. The sick part (to me) is that he is not willing to leave her because he says that they can work things out. I'm sorry, but if that were me and my wife or girlfriend was an idiot for years and cheated on me, there is just no chance that I would stay with her and most likely I would be gone the moment I found out about it.

Why is it that some people decide to stay with someone who treats them like a pile of garbage? This seems to also be a trend with women who are being treated badly by their boyfriends. I have talked to alot of women in bad relationships and they always say that things will be ok.

So the question, what is better, being alone and happy (or neutral) or being in a relationship that sucks?

I pick alone.
