Do you want to share housing but find the transition scary?
Having a home-mate is a big transition. If you are used to living alone it’s an even bigger change. Change requires energy and willingness to accept uncertainty and we don’t like to do it. We much prefer our lives to be predictable. As we get older this tendency gets stronger and we get more entrenched in our ways. It’s pretty common to deny that there’s a need to change until the current situation is so uncomfortable that we have to do something about it. Don’t wait.
