Taking some time out between relationships can be very important; it can give you time to re-evaluate what you have learned in the past and what you may want out of any new relationship. This will change over time - what you wanted five years ago is probably quite different to what you want now.
As we get older, we have to deal with more and more emotional baggage as we embark upon various relationships. Anyone who has been hurt in the past is naturally reluctant to fall in love again, just in case they get hurt again. However, it's important to use these past experiences to understand why previous relationships would never have worked in the first place and as a guide for future dating experiences.
