Well I have been with my husband 5 yrs , I have 4 children 3 boys aged 22,20,12 and 1girl 17. He has two girls aged 32 ,25 who each have 2 children, it's the 32 yr old step daughter I'm having trouble with, at first we got on great , her dad had been single 15 yrs , she was happy for us . I always knew she was jealous of her younger sister as it showed from day 1. But I wouldn't involve myself in it.
