Due to a relationship breakup, I now live with my sister who is one year older than me. I pay £450pcm for a room in her house. Moved in, in Jan and hope to be out before summer as I've bought my own house. She has recently (last night) reignited with someone who she wants to have a sexual relationship with. She has therefore proposed that I stay elsewhere occasionally when she wants him around for sex.
I think this is unfair because she wouldn't treat a friend or a regular tenant this way. I feel she's taking advantage of my position as her sister, who needs a roof over her head. I'm a teacher and my weekends are precious to me, the thought of having to find somewhere to stay on the weekends for the nights she wants him round seems awful to me.
She thinks I'm being unreasonable and will not see my point of view.
Please give me your honest opinions, I plan to show her the thread either way.
