SIngle Female Seeking Home Ownership :

“When you don’t have parents or parental figures limiting the time you spend with your sweetheart (as well as supervising how you spend that time), you’re likely to spend too much time with too little (commitment) in return. As Maken writes, ‘just as familiarity breeds contempt, access breeds complacency. Our solo living arrangements send a signal to men that they can have access into our lives and apartments at any time.’ In the past, ‘men married because they realized that their access to women was going to be constantly monitored by their parents.’”

Although I do not agree with the some of the article it does make a good case to guard your heart against unmotivated men towards commitment.
