Eldest dsd is 15. She has a17 year old boyfriend, they have been together7 months. He currently lives about 10 miles away and she normally sees him for one day on the weekends she's with us. We do all the fetching and carrying.
When dsd is with mum he gets a bus to their house but often stays for nights at a time, not unusual for him to stay Friday, Saturday and Sunday night. AS Far as I'm aware they are not having sex and sleep in separate rooms at mums, although that isn't what this is about.
Boyfriend is moving about 40 miles away soon. A few Weeks ago dsd sent her dad a text saying her and her boyfriend had decided that when he moves away they will have a two week rota, so she will stay at his for two weekends, Friday to Monday and then the following two weekends, they will spend at mums or ours together. this ensures she is rota compliant with us so mum gets her break and assumes that we will do all the running around. Bearing in mind dp already does 250 miles in an average weekend this adds on another 160. Mum won't do any running around so will either put dsd on a train and expect us to pay for it or will expect dp to do it on both weekends.
Dp doesn't want him here all weekend as don't I. It's hard enough having am extra four people here. Dp is saying all the right things and has even said he is prepared for dsd to vote with her feet. Apparently mum thinks the idea she has for the weekends is a good one. [Hmm].
