Sounds like a bit of a nightmare really.If i were u id be looking out for another flat or flat mate!! I think the one youve got will start to do your head in sooner rather than later
You might be better of finding one or 2 good regular girls rather than shagging about this may keep the social bullshit to a minimum.
Either way you`ll always get some as small town people are also nosey as fuck people as theres usually little to do other than poke their nose in others goings on and judging them on it!!
