I kind of understand...
And I think like the biggest biatch!!!
I have 2 step daughters, DSD (Age 13) lives with us and its great. She is a dream step child and we get along better than she does with her dad... However DSD (age 12) is a different story. We clash 24/7. She hates me and my DS (from my previous marriage) and makes sure we know it but she doesn't do it in front of DP so he doesn't see it... She is a massive handful with all kinds of issues that her mother sweeps under the rug. Every fortnight I am filled with anxiety at how I'm going to deal with her and keep the peace so everyone has a good weekend. I hate to think how I would cope if she were to come live with us...
I hate that I feel like this - I love kids!! I feel like a failure because of it...
