I've recently travelled to England from Spain with my four young children to visit our family over the summer holiday's. On the first day of arriving I was already unhappy with the arrangements in my parents house. My sister, who is 25 and is now living with my parents, is currently single but is sleeping with a man for her own sexual pleasures. Now, many of you might think this is ok, except she is sleeping with him in my parents house and he is also staying the night whilst my children and I are here. I've stressed my concerns with my parents and I've asked my parent if while we are here, can they ask my sister not to bring this man into the house, but they refused. They both seem to think this is ok and she can have anybody she wants over to sleep with her even while we are here. I've also spoken to my older sister who has got four children and she also thinks this is ok. Please, can you give me some advice as to what I could do!?! I haven't got enough money to stay somewhere else neither have I got anywhere else we could go. I can just leave as I love on Spain.
