So I have a roommate now that let me move in too a house that he owns. I had thoughts that he was only was letting me move in because he wanted to get closer with my sister and possibly date her. So I confronted him about it and he said no that’s not the reason and so I took his word for it now i think I was right he has invited me out to go places many times to hang out and I agreed to go with him every once in a while but not every time and now we have a descent relationship and at this point I know he is somewhat of a psychopath but I’ll be honest I know I’m playing with fire here but I need a place to stay lol. Now today he invited me to a party at his parents house come to find out it wasn’t a party... it was a small get together with his parents and siblings....  and when I got there his dad acted like he didn’t care that I was there and the second he found out that my sister was my sister he automatically started trying to talk to me and give me some weird type of special treatment he even said oh I met your sister she is a nice girl. 😐 the whole thing was weird and now the roommate texting me if I wanted to go again to his parents house but this time with my sister wth..... idk what to do any advice would help.
