I great up traveling with my military family. I longed to be home - just to be home was my dream. We moved every 2-3 years. It was very hard.
Also I realized I was gay when i was 15 and was told so many many times that it was wrong and that there was something wrong with me, and I was not normal, etc...etc....
That took a long time to get over too. Coming from the South, that was just not a routine occurance and it wasn't until we moved to California that I realized I could be gay and it was no big deal. People did not look down on me, people would not be afraid to leave their kids with me, I could be open and authentic at my job and I could get married. At the time, it seemed like a dream come true, but now ahhh.....so many problems are associated with being authentic.
And then when our son was gravely ill with cancer, my WAW did run into an EA and yes, I knew then she would leave. We had a second child - she called her our fix it baby and that gave us another 6 years.
So there you have it, unresolved issues, running away when life gets tough and throw in unresolved issues from childhood and you have a whole stew of miscommunication, fear, anger and guilt and lack of trust issues.
