I’ve had my fair share of sexual harassment but lately I’m in a situation I don’t know what to do about…
So short side note first, I live in a flat that is connected to another one though we are 2 separated flats (it’s difficult to explain).
I’ve lived there for 2.5 years now and one of the tenants living in the adjacent flat as been kind of stalking me since I moved in. It started with inappropriate messages (let’s go swimming together/how about we have a drink in my room tonight) and escalated to an kiss I did not consent to. I have been ignoring him since the beginning but he just doesn’t stop (even for the short period of time he had a girlfriend!). Last Saturday I was invited to a birthday party of his flatmate (we get along really well and he’s a genuinely nice person), and while there I kissed another guy. Afterwards my stalker interrogated my flatmate if that was normal behaviour for me (specifically going out to meet guys to sleep with), started mopping around and at the end insulted me before hugging me (again against my consent) telling me he didn’t mean it. I told him that he definitely meant it and if he still feels bad about it when sober to come over and apologise. Which I’ve been waiting for since.
As a student in a city with high rental prices I can’t afford another place. And since he knows where to draw the line (we are both law students) or only acts inappropriately when inebriated (try proving intent) there is nothing I can do since (according to the law and the police) he didn’t overstep any law.
I’m just happy my flatmate and friends understand and help me to avoid situations where we are alone. It just annoys me that there is nothing I can do and I’m scared of telling him no outright cause he might sneak in at night/when I’m home alone (I can’t stay locked in my room the whole day).
