On vacation this weekend with us. For those who don't know, SD10 isn't DH's, but he is the only dad SD10 has ever known. SD10 lives with Custodial Gma, BM's mom. The main issues are 1) SD10 lives with Gma, and SD8 lives with BM and is VERY resentful that she(SD8) can't live there or here, but has to stay at BM's at this point. And 2) B/c of how she treats them, SD10 and DD8 leave SD8 out or ignore her. DH doesn't want to deal with all the drama that goes along with all this, so he is on the fence about SD10 going. My issue is that he already told her weeks ago she could go, and that going back on it would not be right. I think all three of them need to be talked to and re-told the rules and consequences, and that they all can go. Oh, and the vacation is with my mom's family, for 4 days to the water park, amusement park, and Amish country. There will be other kids to play with.
