You need to find a university that suits you and that you feel comfortable in - so does your boyfriend. This means that you'll probably be at different unis, but there are many that are close to each other, so maybe this is something to look into? (For example, Uni of Bath and Bath Spa, Uni of Manchester, Machester met)
I'm currently second year and I've been with my boyfriend for over a year and a half, and he's only just started uni. Long distance does work as long as you're both totally honest with each other about your feelings. Some people can't hack it, but if you feel like you're both committed to each other it can work. Obviously, it gets hard sometimes, but you just have to work through it together.
If you do end up at the same uni, do not move in together. Firstly, you need your own space and 'me' time, it'll help ground you. Secondly, as you have stated, you may break up and living together will be awkward for you and the other people you live with. Some of my friends that live with each other broke up, they are still civil with each other, but it's still awkward at times for everyone else that lives in the house. Thirdly, you need to make your own friends - if you're constantly with your boyfriend, it'll be hard to find your own feet with the people that live with you.
I hope this is helpful, good luck!
