If youre going to be married then do life together. If youre only playing humpty dumpty sleep over then get rid of him. Obviously you dont want what ge wants, you dont want to be on time for lectures and you want to be alone so do it. I dont know why any man would put up with your attitude unless you have a lot of money or something.
