Hurting

Hey was wondering if anyone could offer me advice please?

This guy that I was supposed to be seeing pulled one girl and slept with another girl the other night. I am absolutely devastated. He doesn't even care either, I text him to let him know I knew and his reply was 'Yeh I'm sorry, not much I can say.'

I am so angry, we weren't supposed to be seeing other people, I had had my doubts with his lack of contact but I gave him an ultimatum on friday as to what was happening between us and he said he still wanted to meet up when I got back to uni. He even texting me the night he slept with her - before I am presuming.

I just feel so hurt and confused - he is my first real hurt and guy that I've liked and it feels rubbish. What's worse is when I do go back to uni I have a part time job which involves working with him (in a much higher up position than me - he can make my life hell if he wants) and also with the girls he cheated with.

Has anyone got any advice on how to act and get over him? Thank you.

Thank you for your reply. I am tryng not to think about it but it still hurts. I trusted him and believed that he liked me - how wrong was I? I can't believe one minutes he's nice the next he is treating me with no respect at all. He hasn't even apologised.
