No matter how deep the pain the truth of the situation if you allow it will set you free. Acceptance will free the mind, heart, body and soul. It is what it is.
There are certain people who will abandon or cut ties that to them bring no benefit. Love does not even play in their game of life.
There is so much at stake in any relationship, but also so much real hope and comfort. Take your dearest one out somewhere special and show them just how much you care. Make them feel like they are number one in your life. Perhaps in turn they will treat you accordingly. Heal any past problems by taking the time to talk and to listen
Regardless of whether you are looking for a new romance right now or not, you'll have lots of fun meeting new people and flirting up a storm. People will be flirting right back, too -- and if you want more, you should encourage it. But if you don't, don't send mixed signals. You could be biting on more than you can chew. Nip things in the bud, be gentle and kind -- but say what you really mean and tell them what you really want.
There is no such thing as a waste of time when you use the experience wisely. Remember that you can learn from any situation, and there is a lesson in everything.
