20 years ago I married a man with 3 very young boys, I hadn2 young boys too and he and I had one more. The marriage was happy, but we had some money difficulties and the kids often didn't have a lot. My kids are adults now, and my stepchildren resent us like crazy. My husbands parents have a great deal to do with this, but it's driving me crazy! I have a great relationship to the other boys, but every time I interact with his kids I obsess over what we might have done wrong, feel extremely angry and CANNOT let it go. My stomach hurts, I can't sleep and I ruminate on it over and over. What can I do!
