Many cohabitants simply lose the excitement of being married. The inertia, personal choice or afraid to commit keep people from tying the knot and living together is simply easier. This is in particular to those who are afraid to make the commitment to marriage and the ones who become most likely to divorce in the long run. It is especially frustrating if one person in the relationship wants to move to marriage and the other doesn’t. The commitment phobes prefer to “play house” rather than get married. They like the conveniences that living together provides but aren’t convinced this is the person they want to marry and use the inertia momentum to their advantage.
