Hi leona, This treatment is really terrible when you live with someone. Usually the person who does it has emotional problems. It's definitely antagonistic and causes a hostel environment. Generally, a person who becomes "silent" for long periods [days, weeks, ect.,] of time, is also because they can't, or do not have the ability to express there feelings. I'll tell you this, it can escalate and cause an increase in intensity to where the person can become worse. Have someone deal with this person if you cannot break them from, what I consider, a habit that borders on mental abuse...before it gets out of control. Good luck!
