There is a big communication gap between prison and civilian life. Support can be turned into dependence very quickly. In prison, there is minimal consideration for what goes on beyond those walls. Our loved ones can become very selfish, angry, and needy. There may be times where you question yourself "who is this person"? There may also be times where rage takes over and things go completely haywire.
My advice: COMMUNICATE! The negative emotions your loved one shows toward you are not about you! You have to have thick skin when walking this path. The stress of incarceration alone can wear a person down. Prepare yourself for anything but DO NOT SETTLE FOR ANYTHING! Allow your feelings to be heard, allow your loved one to share, and communicate with respect.
This is the BEGINNING! Don't let it END YOU!
