I need help!! (Roast Me)

Me and my bf broke up 2 days ago, we still live in a student house share, to break my contract would be VERY costly and I'm a student, so I already have no money in the first place. Basically there is no choice but to stay here for the year.

Regardless, we've been separated 2 days and yet we've slept with each other 3 times and spent all our free time together. This situation is not healthy for me, but I can't seem to stay away - after all I still love him. We mutually ended things because we only ever seem to argue and we felt like we have nothing in common - but the love is still there. I need some hard hitting honesty here to get me out of this, like tell me I'm a fool for putting myself and him through this. I know we're both being weak, so I need someone to give me a wake up call. Any help would be appreciated, don't hold back :)
