Hi. I've been divorced for 7 years, with an 11 year old child. She spends every other weekend with her father. Today he said he wants her every other week this summer. Can he do this? I know he has rights, but for 7 years he never kept her longer than a weekend. She doesn't want to go, I don't want her to go. Can I prevent this from happening? I live in Indiana and have primary physical custody. Thanks.
