I prefer it no colder than 75 degrees, she likes it cold at 60 degrees. I can't move because the rent is hilariously cheap. Wondering if I could put a heater in my bedroom only, if it would also heat up the entire house? I just want my bedroom warm but her bedroom is right next door, would a heater in my room effect her? I have no idea why she likes it so cold and complains if it's too warm. But I do not want to freeze this winter!
