Lobster she will probably be very influenced by your thoughts on this. What about if the boyfriend lives in a shared house with her and some others, so there isn't such a big division between her and her student friends; then if necessary it would be easier for him to find somewhere else to live if all went pearshaped. I shared a student house with my boyfriend at the time but with various other people in the house too, and we had our own rooms. It might not seem so neat/economical, but I think it can make it easier when you have your own territory. But to suggest that is a bad idea for them to live together might be too heavy handed, I think there could be another option. Actually I would be more concerned about him, being the one left out.
Haudin I hope the part time plan can be made to work financially, it does sound really hopeful. But what a lot of extra work for you to arrange 
Alternatively try and convince her to change courses so that she is nearer home?????
I've been having difficulty trying to convince ds1 that he would be well placed to take a work placement sandwich year. He rang me up babbling about some thing that was annoying him in the media, and then blurted out that he couldn't cope with trying to organise the work placement and didn't even know who to ask in his department. I did feel I was beating my head against a brick wall...I cannot at this stage in his life ring up people and ask them anything, it all has to come from him. After about 10 minutes of arguing with him, I suddenly realised that, foolish as he was being, it was in fact his life and if he didn't want to do the highly useful work placement year, well, that was his decision. So I left it. And told him he needed to get a job in the holidays as a matter of urgency for his confidence. And he seemed a bit more convinced of this necessity. But I was pleased that he likes it there so much that he doesn't want to interrupt his studies. He is in a musical,and seemed quite busy, too busy to come back for the weekend delicious food even though he said he was stressed and struggling to fit in organising everything food/academic work. He also said that he now wished he wasn't in halls because it was a bit too regimented, too many firedoors and security fobs. So obviously now worrying about next year and accommodation from the face of it..
Ds2 struggling with his history coursework for year 13 A level. It seems like only yesterday you were all talking about A level history coursework for our "students" 
Ds1 didn't do history A level so it is new experience for me. So far all the books he is dipping into, appear fascinating. (though I fear to me, not him)
