You know? I don't know why I'm being such a hard a--. I had the very same problem. I felt guilty, so I did everything I could for my son. I didn't have the complication of a step child, but I did have a new husband. It was beyond impossible until my son finally moved out in his mid 20s, because my loyalties were constantly divided.

I wish you the best. I know this is a very hard time.
