I know how you feel. I am in the position and moving out to give us both some space would be ideal but its not an option. The arguments are frequent and I hate them. They take so much out of you emotionally and mentally. If they resolved anything it would be worth it but they do not.
I avoid such confrontations but it is very difficult when the other person deliberately looks for an arguement because they are bored. If you can, move out - you will be surprised how well you would get along if you were not living in the same house.

take care,
S.
