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.
Trying to get back that smile without a memory from the broken relationships seems impossible.
