I think that where you go from here should depend a lot on what the arguments are about. If the two of you have fundemental differeces in what you expect out of your relationship; expectations that neither of you are willing to compromise on, then this isn't something that any amount of argument can resolve.
If on the other hand the arguments are more along the line of bickering, then perhaps you both need to take a deep breath, cool down, walk away, and agree to talk later.
Basically, you should be thinking about if there are any possible solutions, if there aren't even any reasonable compromises or solutions to the problem then there is no point in argueing, and perhaps it's time to part ways.
If there are solutions think about what they are, and try to talk about possible changes together in a non-argumentative fashion. The one thing that is relatively obvious to me after reading your e-mail is that something has to give.

Best of luck,
