I think I have PTSD from having adult step kids, and step grandchildren. I have been a step parent to 3 girls for almost 40 years. I always tried to treat them the same as my bio step children. When raising them we had them every other weekends. I drove 200 miles one way to get them each weekend, then my husband and I would take them home on Sunday.We paid child support though we did get behind at times but always got caught up. We were 3 weeks behind one month because we bought school supplies and a few out fits to help out. When we went on vacation they went with us or we didn't go.
