This would have to depend on the argument. There will always be arguments, no doubt about it. What happens in the arguments would determine the outcome.
I have noticed that a lot of arguments are not about "What can we do to fix the situation" but "Whose fault is it". I don't care whose fault it is, that doesn't fix the problem. Placing blame is not about resolving issues, but "winning" the argument. Fine, it's my fault, you win, I lose. Don't expect me to stick around for the next argument, though.
Why is there a problem? For example, I don't like to shower at night because I usually wake up sweaty. My girlfriend would HATE for me to go to bed without showering. If she hadn't told me that, I wouldn't know about it. Talk to each other. What is the problem, why is it a problem, and what do you think should be done to resolve it? The problem isn't going to mysteriously fix itself.
Don't argue when you're mad. Just leave each other alone for a while, then get back to the issue when you're calm. Angry feelings do not make for logical, rational solutions.
Unless the issue is that you're not getting enough action, sex isn't going to resolve the issue. Address the problem, don't just cover it up or expect it to go away. Makeup sex is for AFTER you're finished solving the problem, not as a replacement for it.
Work together. If I ask you what you want me to do about the problem, don't tell me "fix it". If I don't have a problem with it, my solution is to not change a thing. Work together to find a solution that works for both of you.
If a girl is willing to work towards a solution, then I'd be happy to stay with her. If a girl is willing to blame me for everything and decide that I'm the bad guy in the relationship, then I'll just go back to being single where there is no good guy/bad guy. Simple as that.
