I am a step parent to 2 boys 13 and 9. When I first met my husband of 2 years now I thought that I would be able to handle it. The boys are also from different mothers. So there are 2 ex wives involved. Now that we have our own children 15 months and 3 months things have just gotten to complicated. I feel such strong resentments against his other kids that it is totally consuming me. I am this horrible person that I don't even know. I feel selfish and I am angry all the time.
