Hello, I've been raising my stepson for 10 years now. I met my wife and we got married. At the time she had a 5 year old son. We have definitely strugged throughout the years. We now have two daughters under 9 that are biologically mine. I have been having these feelings kind of like my gas tank is on empty on being a stepfather. I feel awful at times that I feel this way but I sometimes just can't fight these feelings. I know at this piont that I am treating my stepson different than my two daughters. I was wondering if anybody else has had feelings like this. I can say that my marriage is really at a bad place.
