Slightly harsh I think Spoc..
Hi there,
If you are still sleeping with him then u are never going to get over him really.
If you want to be with him, tell him and see if you can work things out. Work around your exams and his work, I'm sure if you really care for each other, you can work something out.
If not, then you have to stop seeing him, otherwise it's going to be hard to get on with things.
Don't you have any other friends that you can go out with at the weekend to take your mind off things and someone that you can also talk to.. :-)
