Not everyone sees themselves in a marriage/co-habiting relationship. I have lived on my own now for more than 17 years and don't regret the decision I made. Whether you choose it as a lifestyle or it's a temporary measure, you can gain a lot from living alone.
1. Peace and Quiet
One of the benefits of living alone is the simple fact that you can have as much peace and quiet as your heart desires! Having housemates can be fun, but there comes a certain time in your life when you want come home to a tranquil setting at the end of a hard day, and living alone is the only way that that possibility is going to be a certainty!
