Step Talk

I haven't had to post on here for a while. Things have been surprisingly well lately. We made it on our lake trip with my family. All 3 SK's came with. They cut the trip short because of school obligations, but behaved most of the time and we all had fun. We didn't have them for the next 2 weeks so things have been smooth for a while now. So BM approached DH about taking the kids every other week again. I think he is starting to consider it. We had decided that is wasn't affordable for us after we pay her full child support. She refused to come down on child support even if she only had them half the time so we stuck with the every other weekend plan we have now. DH is going to call CS tomorrow to see what he can do if if is keeping the kids 50%. I don't think either should pay anything if they are both caring 50%.
DH called me all upset tonight because his oldest SD14 wanted to spend the night and BM said ok, but she had to go to church with them tonight and then she can come back. Dh was livid, he doesn't want BM to force SD to got o church, she is "anti-religion" and hates church. Personally I don't think it is going to hurt her to make her go and since technically it is BM's weekend it's her decision. DH doesn't allow BM to dictate what the SK's do on his time, and I don't think he has a right to tell her SD shouldn't go to church on BM's time. I also don't think it's any of my business to tell either of them what to do with the SK's so I didn't say much except that he doesn't want her to tell him what to do, and he shouldn't tell her. Should I be more involved with what goes on with the SK's and how DH parents? Some of the ways DH parent really bother me and having the kids more could mean a huge change in my life and routine. How do I do that with out DH thinking I am overstepping my bounds.
