Divorced Grandparents continued

Byrd,
It has been heavy on my mind that there are factions of family, the blood families their own units. I feel rejected by my step mother and step siblings and I feel angry for treating them or ever thinking of them as full family. It is like one of those economics experiments where they test to see if you all work together so everyone gets more or if one person will trick the others to gain more for them self. I was raised by my Dad and Stepmom to treat all the family as family, and now the step family are clearly more true and more loved for each other. All this time I could have been investing more in my blood family. The worst part is that the step family does it since they feel left out, there are more of us, we seem to have more earning potential (though not realized), and we have more degrees. I know it does not help to be angry or hurt. But I feel that way. I feel like the step family is family when they feel like it, but I am always something that can be dropped. That feels shitty.
I will feel very very good if at the end of my life I have kept one family together, we all live and love each other. I would hate to be a step mother, it is so confusing.
Love,
Mom
