Trying to get back that smile without a memory from the broken relationships seems impossible.
An emotional bond with that special someone presents a woman with an over-the-top feeling; but then at the same is painful when that very bond breaks. A break-up can be destructive to women morale and confidence; the best way to get over it is to make sure that you pin-point your priorities. Keep yourself busy with schedules, socialize without that nagging guilt. Moreover, if you still have time and thoughts of your relationship to kill; work towards your passions, focus on that dream project you always wanted to realize and did not enough time to do so in the past.
