What are your options? Can things be worked out with him - schedule about housecleaning, clear expectations about cleaning supplies/costs? The standing too close, intrusiveness, eyeing - how to go about changing this behaviour? About the girlfriend and their time together - maybe find a way to communicate to both of them that you can hear them (and it's disrupting your sleep). Hope you can sort through things. Or will he leave? Or will he change? Or will you leave? Or will you change?
